Introduction

cmake-modules - Reference of available CMake modules.

------------------------------------------------------------------------------
Description

The "cmake" executable is the CMake command-line interface. It may be used
to configure projects in scripts. Project configuration settings may be
specified on the command line with the -D option. The -i option will cause
cmake to interactively prompt for such settings.

CMake is a cross-platform build system generator. Projects specify their
build process with platform-independent CMake listfiles included in each
directory of a source tree with the name CMakeLists.txt. Users build a
project by using CMake to generate a build system for a native tool on their
platform.

------------------------------------------------------------------------------
Standard CMake Modules

The following modules are provided with CMake. They can be used with
INCLUDE(ModuleName).

CMake Modules - Modules coming with CMake, the Cross-Platform Makefile Generator.

This is the documentation for the modules and scripts coming with CMake.
Using these modules you can check the computer system for installed software
packages, features of the compiler and the existance of headers to name just
a few.

AddFileDependencies
ADD_FILE_DEPENDENCIES(source_file depend_files...)

Adds the given files as dependencies to source_file

BundleUtilities
Functions to help assemble a standalone bundle application.

A collection of CMake utility functions useful for dealing with .app
bundles on the Mac and bundle-like directories on any OS.

The following functions are provided by this module:

fixup_bundle
copy_and_fixup_bundle
verify_app
get_bundle_main_executable
get_dotapp_dir
get_bundle_and_executable
get_bundle_all_executables
get_item_key
clear_bundle_keys
set_bundle_key_values
get_bundle_keys
copy_resolved_item_into_bundle
copy_resolved_framework_into_bundle
fixup_bundle_item
verify_bundle_prerequisites
verify_bundle_symlinks

Requires CMake 2.6 or greater because it uses function, break and
PARENT_SCOPE. Also depends on GetPrerequisites.cmake.

FIXUP_BUNDLE(<app> <libs> <dirs>)

Fix up a bundle in-place and make it standalone, such that it can be
drag-n-drop copied to another machine and run on that machine as long
as all of the system libraries are compatible.

If you pass plugins to fixup_bundle as the libs parameter, you should
install them or copy them into the bundle before calling fixup_bundle.
The "libs" parameter is a list of libraries that must be fixed up, but
that cannot be determined by otool output analysis. (i.e., plugins)

Gather all the keys for all the executables and libraries in a bundle,
and then, for each key, copy each prerequisite into the bundle. Then
fix each one up according to its own list of prerequisites.

Then clear all the keys and call verify_app on the final bundle to
ensure that it is truly standalone.

COPY_AND_FIXUP_BUNDLE(<src> <dst> <libs> <dirs>)

Makes a copy of the bundle <src> at location <dst> and then fixes up
the new copied bundle in-place at <dst>...

VERIFY_APP(<app>)

Verifies that an application <app> appears valid based on running
analysis tools on it. Calls "message(FATAL_ERROR" if the application
is not verified.

GET_BUNDLE_MAIN_EXECUTABLE(<bundle> <result_var>)

The result will be the full path name of the bundle's main executable
file or an "error:" prefixed string if it could not be determined.

GET_DOTAPP_DIR(<exe> <dotapp_dir_var>)

Returns the nearest parent dir whose name ends with ".app" given the
full path to an executable. If there is no such parent dir, then
return a dir at the same level as the executable, named with the
executable's base name and ending with ".app"

The returned directory may or may not exist.

GET_BUNDLE_AND_EXECUTABLE(<app> <bundle_var> <executable_var> <valid_var>)

Takes either a ".app" directory name or the name of an executable
nested inside a ".app" directory and returns the path to the ".app"
directory in <bundle_var> and the path to its main executable in
<executable_var>

GET_BUNDLE_ALL_EXECUTABLES(<bundle> <exes_var>)

Scans the given bundle recursively for all executable files and
accumulates them into a variable.

GET_ITEM_KEY(<item> <key_var>)

Given a file (item) name, generate a key that should be unique
considering the set of libraries that need copying or fixing up to
make a bundle standalone. This is essentially the file name including
extension with "." replaced by "_"

This key is used as a prefix for CMake variables so that we can
associate a set of variables with a given item based on its key.

CLEAR_BUNDLE_KEYS(<keys_var>)

Loop over the list of keys, clearing all the variables associated with
each key. After the loop, clear the list of keys itself.

Caller of get_bundle_keys should call clear_bundle_keys when done with
list of keys.

SET_BUNDLE_KEY_VALUES(<keys_var> <context> <item> <exepath> <dirs>
<copyflag>)

Add a key to the list (if necessary) for the given item. If added,
also set all the variables associated with that key.

GET_BUNDLE_KEYS(<app> <libs> <dirs> <keys_var>)

Loop over all the executable and library files within the bundle (and
given as extra <libs>) and accumulate a list of keys representing
them. Set values associated with each key such that we can loop over
all of them and copy prerequisite libs into the bundle and then do
appropriate install_name_tool fixups.

COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

Copy a resolved item into the bundle if necessary. Copy is not
necessary if the resolved_item is "the same as" the
resolved_embedded_item.

COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

Copy a resolved framework into the bundle if necessary. Copy is not
necessary if the resolved_item is "the same as" the
resolved_embedded_item.

By default, BU_COPY_FULL_FRAMEWORK_CONTENTS is not set. If you want
full frameworks embedded in your bundles, set
BU_COPY_FULL_FRAMEWORK_CONTENTS to ON before calling fixup_bundle. By
default, COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies the framework
dylib itself plus the framework Resources directory.

FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>)

Get the direct/non-system prerequisites of the resolved embedded item.
For each prerequisite, change the way it is referenced to the value of
the _EMBEDDED_ITEM keyed variable for that prerequisite. (Most likely
changing to an "@executable_path" style reference.)

This function requires that the resolved_embedded_item be "inside" the
bundle already. In other words, if you pass plugins to fixup_bundle
as the libs parameter, you should install them or copy them into the
bundle before calling fixup_bundle. The "libs" parameter is a list of
libraries that must be fixed up, but that cannot be determined by
otool output analysis. (i.e., plugins)

Also, change the id of the item being fixed up to its own
_EMBEDDED_ITEM value.

Accumulate changes in a local variable and make *one* call to
install_name_tool at the end of the function with all the changes at
once.

If the BU_CHMOD_BUNDLE_ITEMS variable is set then bundle items will be
marked writable before install_name_tool tries to change them.

VERIFY_BUNDLE_PREREQUISITES(<bundle> <result_var> <info_var>)

Verifies that the sum of all prerequisites of all files inside the
bundle are contained within the bundle or are "system" libraries,
presumed to exist everywhere.

VERIFY_BUNDLE_SYMLINKS(<bundle> <result_var> <info_var>)

Verifies that any symlinks found in the bundle point to other files
that are already also in the bundle... Anything that points to an
external file causes this function to fail the verification.

CMakeBackwardCompatibilityCXX
define a bunch of backwards compatibility variables

CMAKE_ANSI_CXXFLAGS - flag for ansi c++
CMAKE_HAS_ANSI_STRING_STREAM - has <strstream>
INCLUDE(TestForANSIStreamHeaders)
INCLUDE(CheckIncludeFileCXX)
INCLUDE(TestForSTDNamespace)
INCLUDE(TestForANSIForScope)

CMakeDependentOption
Macro to provide an option dependent on other options.

This macro presents an option to the user only if a set of other
conditions are true. When the option is not presented a default value
is used, but any value set by the user is preserved for when the
option is presented again. Example invocation:

CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
"USE_BAR;NOT USE_ZOT" OFF)

If USE_BAR is true and USE_ZOT is false, this provides an option
called USE_FOO that defaults to ON. Otherwise, it sets USE_FOO to
OFF. If the status of USE_BAR or USE_ZOT ever changes, any value for
the USE_FOO option is saved so that when the option is re-enabled it
retains its old value.

CMakeDetermineVSServicePack
Includes a public function for assisting users in trying to determine
the

Visual Studio service pack in use.

Sets the passed in variable to one of the following values or an empty
string if unknown.

vc80
vc80sp1
vc90
vc90sp1

Usage: ===========================

if(MSVC)
include(CMakeDetermineVSServicePack)
DetermineVSServicePack( my_service_pack )

if( my_service_pack )
message(STATUS "Detected: ${my_service_pack}")
endif()
endif()

===========================

CMakeFindFrameworks
helper module to find OSX frameworks

CMakeForceCompiler

This module defines macros intended for use by cross-compiling
toolchain files when CMake is not able to automatically detect the
compiler identification.

Macro CMAKE_FORCE_C_COMPILER has the following signature:

CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)

It sets CMAKE_C_COMPILER to the given compiler and the cmake internal
variable CMAKE_C_COMPILER_ID to the given compiler-id. It also
bypasses the check for working compiler and basic compiler information
tests.

Macro CMAKE_FORCE_CXX_COMPILER has the following signature:

CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>)

It sets CMAKE_CXX_COMPILER to the given compiler and the cmake
internal variable CMAKE_CXX_COMPILER_ID to the given compiler-id. It
also bypasses the check for working compiler and basic compiler
information tests.

Macro CMAKE_FORCE_Fortran_COMPILER has the following signature:

CMAKE_FORCE_Fortran_COMPILER(<compiler> <compiler-id>)

It sets CMAKE_Fortran_COMPILER to the given compiler and the cmake
internal variable CMAKE_Fortran_COMPILER_ID to the given compiler-id.
It also bypasses the check for working compiler and basic compiler
information tests.

So a simple toolchain file could look like this:

INCLUDE (CMakeForceCompiler)
SET(CMAKE_SYSTEM_NAME Generic)
CMAKE_FORCE_C_COMPILER (chc12 MetrowerksHicross)
CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross)

CMakeParseArguments

CMAKE_PARSE_ARGUMENTS(<prefix> <options> <one_value_keywords>
<multi_value_keywords> args...)

CMAKE_PARSE_ARGUMENTS() is intended to be used in macros or functions
for parsing the arguments given to that macro or function. It
processes the arguments and defines a set of variables which hold the
values of the respective options.

The <options> argument contains all options for the respective macro,
i.e. keywords which can be used when calling the macro without any
value following, like e.g. the OPTIONAL keyword of the install()
command.

The <one_value_keywords> argument contains all keywords for this macro
which are followed by one value, like e.g. DESTINATION keyword of the
install() command.

The <multi_value_keywords> argument contains all keywords for this
macro which can be followed by more than one value, like e.g. the
TARGETS or FILES keywords of the install() command.

When done, CMAKE_PARSE_ARGUMENTS() will have defined for each of the
keywords listed in <options>, <one_value_keywords> and
<multi_value_keywords> a variable composed of the given <prefix>
followed by "_" and the name of the respective keyword. These
variables will then hold the respective value from the argument list.
For the <options> keywords this will be TRUE or FALSE.

All remaining arguments are collected in a variable
<prefix>_UNPARSED_ARGUMENTS, this can be checked afterwards to see
whether your macro was called with unrecognized parameters.

As an example here a my_install() macro, which takes similar arguments
as the real install() command:

function(MY_INSTALL)
set(options OPTIONAL FAST)
set(oneValueArgs DESTINATION RENAME)
set(multiValueArgs TARGETS CONFIGURATIONS)
cmake_parse_arguments(MY_INSTALL "${options}" "${oneValueArgs}" "${multiValueArgs}" ${ARGN} )
...

Assume my_install() has been called like this:

my_install(TARGETS foo bar DESTINATION bin OPTIONAL blub)

After the cmake_parse_arguments() call the macro will have set the
following variables:

MY_INSTALL_OPTIONAL = TRUE
MY_INSTALL_FAST = FALSE (this option was not used when calling my_install()
MY_INSTALL_DESTINATION = "bin"
MY_INSTALL_RENAME = "" (was not used)
MY_INSTALL_TARGETS = "foo;bar"
MY_INSTALL_CONFIGURATIONS = "" (was not used)
MY_INSTALL_UNPARSED_ARGUMENTS = "blub" (no value expected after "OPTIONAL"

You can the continue and process these variables.

Keywords terminate lists of values, e.g. if directly after a
one_value_keyword another recognized keyword follows, this is
interpreted as the beginning of the new option. E.g.
my_install(TARGETS foo DESTINATION OPTIONAL) would result in
MY_INSTALL_DESTINATION set to "OPTIONAL", but MY_INSTALL_DESTINATION
would be empty and MY_INSTALL_OPTIONAL would be set to TRUE therefor.

CMakePrintSystemInformation
print system information

This file can be used for diagnostic purposes just include it in a
project to see various internal CMake variables.

CMakeVerifyManifest

CMakeVerifyManifest.cmake

This script is used to verify that embeded manifests and side by side
manifests for a project match. To run this script, cd to a directory
and run the script with cmake -P. On the command line you can pass in
versions that are OK even if not found in the .manifest files. For
example, cmake -Dallow_versions=8.0.50608.0
-PCmakeVerifyManifest.cmake could be used to allow an embeded manifest
of 8.0.50608.0 to be used in a project even if that version was not
found in the .manifest file.

CPack
foreach generator, it then

The CPack module generates binary and source installers in a variety
of formats using the cpack program. Inclusion of the CPack module
adds two new targets to the resulting makefiles, package and
package_source, which build the binary and source installers,
respectively. The generated binary installers contain everything
installed via CMake's INSTALL command (and the deprecated
INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).

For certain kinds of binary installers (including the graphical
installers on Mac OS X and Windows), CPack generates installers that
allow users to select individual application components to install.
The contents of each of the components are identified by the COMPONENT
argument of CMake's INSTALL command. These components can be
annotated with user-friendly names and descriptions, inter-component
dependencies, etc., and grouped in various ways to customize the
resulting installer. See the cpack_add_* commands, described below,
for more information about component-specific installations.

The CPACK_GENERATOR variable has different meanings in different
contexts. In your CMakeLists.txt file, CPACK_GENERATOR is a *list of
generators*: when run with no other arguments, CPack will iterate over
that list and produce one package for each generator. In a
CPACK_PROJECT_CONFIG_FILE, though, CPACK_GENERATOR is a *string naming
a single generator*. If you need per-cpack- generator logic to
control *other* cpack settings, then you need a
CPACK_PROJECT_CONFIG_FILE.

The CMake source tree itself contains a CPACK_PROJECT_CONFIG_FILE.
See the top level file CMakeCPackOptions.cmake.in for an example.

If set, the CPACK_PROJECT_CONFIG_FILE is included automatically on a
per-generator basis. It only need contain overrides.

Here's how it works:

CPACK_GENERATOR list variable (unless told to use just a
specific one via -G on the command line...)

- sets CPACK_GENERATOR to the one currently being iterated
- includes the CPACK_PROJECT_CONFIG_FILE
- produces the package for that generator

This is the key: For each generator listed in CPACK_GENERATOR in
CPackConfig.cmake, cpack will *reset* CPACK_GENERATOR internally to
*the one currently being used* and then include the
CPACK_PROJECT_CONFIG_FILE.

Before including this CPack module in your CMakeLists.txt file, there
are a variety of variables that can be set to customize the resulting
installers. The most commonly-used variables are:

CPACK_PACKAGE_NAME - The name of the package (or application). If
not specified, defaults to the project name.

CPACK_PACKAGE_VENDOR - The name of the package vendor (e.g.,
"Kitware").

CPACK_PACKAGE_VERSION_MAJOR - Package major Version

CPACK_PACKAGE_VERSION_MINOR - Package minor Version

CPACK_PACKAGE_VERSION_PATCH - Package patch Version

CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the
project. Used, for example, the introduction screen of a
CPack-generated Windows installer to describe the project.

CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the
project (only a few words).

CPACK_PACKAGE_FILE_NAME - The name of the package file to generate,
not including the extension. For example, cmake-2.6.1-Linux-i686.

CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the
target system, e.g., "CMake 2.5".

CPACK_PROJECT_CONFIG_FILE - File included at cpack time, once per
generator after setting CPACK_GENERATOR to the actual generator
being used. Allows per-generator setting of CPACK_* variables at
cpack time.

CPACK_RESOURCE_FILE_LICENSE - License file for the project, which
will typically be displayed to the user (often with an explicit
"Accept" button, for graphical installers) prior to installation.

CPACK_RESOURCE_FILE_README - ReadMe file for the project, which
typically describes in some detail

CPACK_RESOURCE_FILE_WELCOME - Welcome file for the project, which
welcomes users to this installer. Typically used in the graphical
installers on Windows and Mac OS X.

CPACK_MONOLITHIC_INSTALL - Disables the component-based
installation mechanism, so that all components are always installed.

CPACK_GENERATOR - List of CPack generators to use. If not
specified, CPack will create a set of options (e.g.,
CPACK_BINARY_NSIS) allowing the user to enable/disable individual
generators.

CPACK_OUTPUT_CONFIG_FILE - The name of the CPack configuration file
for binary installers that will be generated by the CPack
module. Defaults to CPackConfig.cmake.

CPACK_PACKAGE_EXECUTABLES - Lists each of the executables along
with a text label, to be used to create Start Menu shortcuts on
Windows. For example, setting this to the list ccmake;CMake will
create a shortcut named "CMake" that will execute the installed
executable ccmake.

CPACK_STRIP_FILES - List of files to be stripped. Starting with
CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which
enables stripping of all files (a list of files evaluates to TRUE
in CMake, so this change is compatible).

The following CPack variables are specific to source packages, and
will not affect binary packages:

CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package,
e.g., cmake-2.6.1

CPACK_SOURCE_STRIP_FILES - List of files in the source tree that
will be stripped. Starting with CMake 2.6.0
CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
stripping of all files (a list of files evaluates to TRUE in CMake,
so this change is compatible).

CPACK_SOURCE_GENERATOR - List of generators used for the source
packages. As with CPACK_GENERATOR, if this is not specified then
CPack will create a set of options (e.g., CPACK_SOURCE_ZIP)
allowing users to select which packages will be generated.

CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack
configuration file for source installers that will be generated by
the CPack module. Defaults to CPackSourceConfig.cmake.

CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree
that won't be packaged when building a source package. This is a
list of patterns, e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*

The following variables are specific to the DragNDrop installers built
on Mac OS X:

CPACK_DMG_VOLUME_NAME - The volume name of the generated disk
image. Defaults to CPACK_PACKAGE_FILE_NAME.

CPACK_DMG_FORMAT - The disk image format. Common values are UDRO
(UDIF read-only), UDZO (UDIF zlib-compressed) or UDBZ (UDIF
bzip2-compressed). Refer to hdiutil(1) for more information on
other available formats.

CPACK_DMG_DS_STORE - Path to a custom .DS_Store file which e.g.
can be used to specify the Finder window position/geometry and
layout (such as hidden toolbars, placement of the icons etc.).
This file has to be generated by the Finder (either manually or
through OSA-script) using a normal folder from which the .DS_Store
file can then be extracted.

CPACK_DMG_BACKGROUND_IMAGE - Path to an image file which is to be
used as the background for the Finder Window when the disk image
is opened. By default no background image is set. The background
image is applied after applying the custom .DS_Store file.

CPACK_COMMAND_HDIUTIL - Path to the hdiutil(1) command used to
operate on disk image files on Mac OS X. This variable can be used
to override the automatically detected command (or specify its
location if the auto-detection fails to find it.)

CPACK_COMMAND_SETFILE - Path to the SetFile(1) command used to set
extended attributes on files and directories on Mac OS X. This
variable can be used to override the automatically detected
command (or specify its location if the auto-detection fails to
find it.)

CPACK_COMMAND_REZ - Path to the Rez(1) command used to compile
resources on Mac OS X. This variable can be used to override the
automatically detected command (or specify its location if the
auto-detection fails to find it.)

Installers built on Mac OS X using the Bundle generator use the
aforementioned DragNDrop variables, plus the following Bundle-specific
parameters:

CPACK_BUNDLE_NAME - The name of the generated bundle. This
appears in the OSX finder as the bundle name. Required.

CPACK_BUNDLE_PLIST - Path to an OSX plist file that will be used
as the Info.plist for the generated bundle. This assumes that
the caller has generated or specified their own Info.plist file.
Required.

CPACK_BUNDLE_ICON - Path to an OSX icns file that will be used as
the icon for the generated bundle. This is the icon that appears
in the OSX finder for the bundle, and in the OSX dock when the
bundle is opened. Required.

CPACK_BUNDLE_STARTUP_SCRIPT - Path to an executable or script that
will be run whenever an end-user double-clicks the generated bundle
in the OSX Finder. Optional.

The following variables are specific to the graphical installers built
on Windows using the Nullsoft Installation System.

CPACK_PACKAGE_INSTALL_REGISTRY_KEY - Registry key used when
installing this project.

CPACK_NSIS_INSTALL_ROOT - The default installation directory presented
to the end user by the NSIS installer is under this root dir. The full
directory presented to the end user is:
${CPACK_NSIS_INSTALL_ROOT}/${CPACK_PACKAGE_INSTALL_DIRECTORY}

CPACK_NSIS_MUI_ICON - The icon file (.ico) for the generated
install program.

CPACK_NSIS_MUI_UNIICON - The icon file (.ico) for the generated
uninstall program.

CPACK_PACKAGE_ICON - A branding image that will be displayed inside
the installer.

CPACK_NSIS_EXTRA_INSTALL_COMMANDS - Extra NSIS commands that will
be added to the install Section.

CPACK_NSIS_EXTRA_UNINSTALL_COMMANDS - Extra NSIS commands that will
be added to the uninstall Section.

CPACK_NSIS_COMPRESSOR - The arguments that will be passed to the
NSIS SetCompressor command.

CPACK_NSIS_MODIFY_PATH - If this is set to "ON", then an extra page
will appear in the installer that will allow the user to choose
whether the program directory should be added to the system PATH
variable.

CPACK_NSIS_DISPLAY_NAME - The display name string that appears in
the Windows Add/Remove Program control panel

CPACK_NSIS_PACKAGE_NAME - The title displayed at the top of the
installer.

CPACK_NSIS_INSTALLED_ICON_NAME - A path to the executable that
contains the installer icon.

CPACK_NSIS_HELP_LINK - URL to a web site providing assistance in
installing your application.

CPACK_NSIS_URL_INFO_ABOUT - URL to a web site providing more
information about your application.

CPACK_NSIS_CONTACT - Contact information for questions and comments
about the installation process.

CPACK_NSIS_CREATE_ICONS_EXTRA - Additional NSIS commands for
creating start menu shortcuts.

CPACK_NSIS_DELETE_ICONS_EXTRA -Additional NSIS commands to
uninstall start menu shortcuts.

CPACK_NSIS_EXECUTABLES_DIRECTORY - Creating NSIS start menu links
assumes that they are in 'bin' unless this variable is set.
For example, you would set this to 'exec' if your executables are
in an exec directory.

CPACK_NSIS_MUI_FINISHPAGE_RUN - Specify an executable to add an option
to run on the finish page of the NSIS installer.

The following variable is specific to installers build on Mac OS X
using PackageMaker:

CPACK_OSX_PACKAGE_VERSION - The version of Mac OS X that the
resulting PackageMaker archive should be compatible
with. Different versions of Mac OS X support different
features. For example, CPack can only build component-based
installers for Mac OS X 10.4 or newer, and can only build
installers that download component son-the-fly for Mac OS X 10.5
or newer. If left blank, this value will be set to the minimum
version of Mac OS X that supports the requested features. Set this
variable to some value (e.g., 10.4) only if you want to guarantee
that your installer will work on that version of Mac OS X, and
don't mind missing extra features available in the installer
shipping with later versions of Mac OS X.

The following variables are for advanced uses of CPack:

CPACK_CMAKE_GENERATOR - What CMake generator should be used if the
project is CMake project. Defaults to the value of CMAKE_GENERATOR;
few users will want to change this setting.

CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify
what project to install. The four values are: Build directory,
Project Name, Project Component, Directory. If omitted, CPack will
build an installer that installers everything.

CPACK_SYSTEM_NAME - System name, defaults to the value of
${CMAKE_SYSTEM_NAME}.

CPACK_PACKAGE_VERSION - Package full version, used internally. By
default, this is built from CPACK_PACKAGE_VERSION_MAJOR,
CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.

CPACK_TOPLEVEL_TAG - Directory for the installed files.

CPACK_INSTALL_COMMANDS - Extra commands to install components.

CPACK_INSTALL_DIRECTORIES - Extra directories to install.

Component-specific installation allows users to select specific sets
of components to install during the install process. Installation
components are identified by the COMPONENT argument of CMake's INSTALL
commands, and should be further described by the following CPack
commands:

cpack_add_component - Describes a CPack installation component
named by the COMPONENT argument to a CMake INSTALL command.

cpack_add_component(compname
[DISPLAY_NAME name]
[DESCRIPTION description]
[HIDDEN | REQUIRED | DISABLED ]
[GROUP group]
[DEPENDS comp1 comp2 ... ]
[INSTALL_TYPES type1 type2 ... ]
[DOWNLOADED]
[ARCHIVE_FILE filename])

The cmake_add_component command describes an installation
component, which the user can opt to install or remove as part of
the graphical installation process. compname is the name of the
component, as provided to the COMPONENT argument of one or more
CMake INSTALL commands.

DISPLAY_NAME is the displayed name of the component, used in
graphical installers to display the component name. This value can
be any string.

DESCRIPTION is an extended description of the component, used in
graphical installers to give the user additional information about
the component. Descriptions can span multiple lines using "\n" as
the line separator. Typically, these descriptions should be no
more than a few lines long.

HIDDEN indicates that this component will be hidden in the
graphical installer, so that the user cannot directly change
whether it is installed or not.

REQUIRED indicates that this component is required, and therefore
will always be installed. It will be visible in the graphical
installer, but it cannot be unselected. (Typically, required
components are shown greyed out).

DISABLED indicates that this component should be disabled
(unselected) by default. The user is free to select this component
for installation, unless it is also HIDDEN.

DEPENDS lists the components on which this component depends. If
this component is selected, then each of the components listed
must also be selected. The dependency information is encoded
within the installer itself, so that users cannot install
inconsitent sets of components.

GROUP names the component group of which this component is a
part. If not provided, the component will be a standalone
component, not part of any component group. Component groups are
described with the cpack_add_component_group command, detailed
below.

INSTALL_TYPES lists the installation types of which this component
is a part. When one of these installations types is selected, this
component will automatically be selected. Installation types are
described with the cpack_add_install_type command, detailed below.

DOWNLOADED indicates that this component should be downloaded
on-the-fly by the installer, rather than packaged in with the
installer itself. For more information, see the cpack_configure_downloads
command.

ARCHIVE_FILE provides a name for the archive file created by CPack
to be used for downloaded components. If not supplied, CPack will
create a file with some name based on CPACK_PACKAGE_FILE_NAME and
the name of the component. See cpack_configure_downloads for more
information.

cpack_add_component_group - Describes a group of related CPack
installation components.

cpack_add_component_group(groupname
[DISPLAY_NAME name]
[DESCRIPTION description]
[PARENT_GROUP parent]
[EXPANDED]
[BOLD_TITLE])

The cpack_add_component_group describes a group of installation
components, which will be placed together within the listing of
options. Typically, component groups allow the user to
select/deselect all of the components within a single group via a
single group-level option. Use component groups to reduce the
complexity of installers with many options. groupname is an
arbitrary name used to identify the group in the GROUP argument of
the cpack_add_component command, which is used to place a
component in a group. The name of the group must not conflict with
the name of any component.

DISPLAY_NAME is the displayed name of the component group, used in
graphical installers to display the component group name. This
value can be any string.

DESCRIPTION is an extended description of the component group,
used in graphical installers to give the user additional
information about the components within that group. Descriptions
can span multiple lines using "\n" as the line
separator. Typically, these descriptions should be no more than a
few lines long.

PARENT_GROUP, if supplied, names the parent group of this group.
Parent groups are used to establish a hierarchy of groups,
providing an arbitrary hierarchy of groups.

EXPANDED indicates that, by default, the group should show up as
"expanded", so that the user immediately sees all of the
components within the group. Otherwise, the group will initially
show up as a single entry.

BOLD_TITLE indicates that the group title should appear in bold,
to call the user's attention to the group.

cpack_add_install_type - Add a new installation type containing a
set of predefined component selections to the graphical installer.

cpack_add_install_type(typename
[DISPLAY_NAME name])

The cpack_add_install_type command identifies a set of preselected
components that represents a common use case for an
application. For example, a "Developer" install type might include
an application along with its header and library files, while an
"End user" install type might just include the application's
executable. Each component identifies itself with one or more
install types via the INSTALL_TYPES argument to
cpack_add_component.

DISPLAY_NAME is the displayed name of the install type, which will
typically show up in a drop-down box within a graphical
installer. This value can be any string.

cpack_configure_downloads - Configure CPack to download selected
components on-the-fly as part of the installation process.

cpack_configure_downloads(site
[UPLOAD_DIRECTORY dirname]
[ALL]
[ADD_REMOVE|NO_ADD_REMOVE])

The cpack_configure_downloads command configures installation-time
downloads of selected components. For each downloadable component,
CPack will create an archive containing the contents of that
component, which should be uploaded to the given site. When the
user selects that component for installation, the installer will
download and extract the component in place. This feature is
useful for creating small installers that only download the
requested components, saving bandwidth. Additionally, the
installers are small enough that they will be installed as part of
the normal installation process, and the "Change" button in
Windows Add/Remove Programs control panel will allow one to add or
remove parts of the application after the original
installation. On Windows, the downloaded-components functionality
requires the ZipDLL plug-in for NSIS, available at:

http://nsis.sourceforge.net/ZipDLL_plug-in

On Mac OS X, installers that download components on-the-fly can
only be built and installed on system using Mac OS X 10.5 or
later.

The site argument is a URL where the archives for downloadable
components will reside, e.g., http://www.cmake.org/files/2.6.1/installer/
All of the archives produced by CPack should be uploaded to that location.

UPLOAD_DIRECTORY is the local directory where CPack will create the
various archives for each of the components. The contents of this
directory should be uploaded to a location accessible by the URL given
in the site argument. If omitted, CPack will use the directory
CPackUploads inside the CMake binary directory to store the generated
archives.

The ALL flag indicates that all components be downloaded. Otherwise, only
those components explicitly marked as DOWNLOADED or that have a specified
ARCHIVE_FILE will be downloaded. Additionally, the ALL option implies
ADD_REMOVE (unless NO_ADD_REMOVE is specified).

ADD_REMOVE indicates that CPack should install a copy of the installer
that can be called from Windows' Add/Remove Programs dialog (via the
"Modify" button) to change the set of installed components. NO_ADD_REMOVE
turns off this behavior. This option is ignored on Mac OS X.

CPackDeb
The builtin (binary) CPack Deb generator (Unix only)

CPackDeb may be used to create Deb package using CPack. CPackDeb is a
CPack generator thus it uses the CPACK_XXX variables used by CPack :
http://www.cmake.org/Wiki/CMake:CPackConfiguration. CPackDeb
generator should work on any linux host but it will produce better deb
package when Debian specific tools 'dpkg-xxx' are usable on the build
system.

CPackDeb has specific features which are controlled by the specifics
CPACK_DEBIAN_XXX variables.You'll find a detailed usage on the wiki:

CPACK_RPM_PACKAGE_RELOCATABLE
Mandatory : NO
Default : CPACK_PACKAGE_RELOCATABLE
If this variable is set to TRUE or ON CPackRPM will try
to build a relocatable RPM package. A relocatable RPM may
be installed using rpm --prefix or --relocate in order to
install it at an alternate place see rpm(8).
Note that currently this may fail if CPACK_SET_DESTDIR is set to ON.
If CPACK_SET_DESTDIR is set then you will get a warning message
but if there is file installed with absolute path you'll get
unexpected behavior.
CPACK_RPM_SPEC_INSTALL_POST

spec file and stop with an error. For example launch CPack like this
cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM
The user may then use this file in order to hand-craft is own
binary spec file which may be used with CPACK_RPM_USER_BINARY_SPECFILE.
CPACK_RPM_PRE_INSTALL_SCRIPT_FILE
CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE
Mandatory : NO
Default : -
May be used to embbed a pre (un)installation script in the spec file.

put after the %pre or %preun section
One may verify which scriptlet has been included with
rpm -qp --scripts package.rpm
CPACK_RPM_POST_INSTALL_SCRIPT_FILE
CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE
Mandatory : NO
Default : -
May be used to embbed a post (un)installation script in the spec file.

Mandatory : NO
Default : -
May be used to embbed a changelog in the spec file.
The refered file will be read and directly put after the %changelog
section.

CTest
Configure a project for testing with CTest/CDash

Include this module in the top CMakeLists.txt file of a project to
enable testing with CTest and dashboard submissions to CDash:

project(MyProject)
...
include(CTest)

The module automatically creates a BUILD_TESTING option that selects
whether to enable testing support (ON by default). After including
the module, use code like

if(BUILD_TESTING)
# ... CMake code to create tests ...
endif()

to creating tests when testing is enabled.

To enable submissions to a CDash server, create a CTestConfig.cmake
file at the top of the project with content such as

set(CTEST_PROJECT_NAME "MyProject")
set(CTEST_NIGHTLY_START_TIME "01:00:00 UTC")
set(CTEST_DROP_METHOD "http")
set(CTEST_DROP_SITE "my.cdash.org")
set(CTEST_DROP_LOCATION "/submit.php?project=MyProject")
set(CTEST_DROP_SITE_CDASH TRUE)

(the CDash server can provide the file to a project administrator who
configures 'MyProject'). Settings in the config file are shared by
both this CTest module and the CTest command-line tool's dashboard
script mode (ctest -S).

While building a project for submission to CDash, CTest scans the
build output for errors and warnings and reports them with surrounding
context from the build log. This generic approach works for all build
tools, but does not give details about the command invocation that
produced a given problem. One may get more detailed reports by adding

set(CTEST_USE_LAUNCHERS 1)

to the CTestConfig.cmake file. When this option is enabled, the CTest
module tells CMake's Makefile generators to invoke every command in
the generated build system through a CTest launcher program.
(Currently the CTEST_USE_LAUNCHERS option is ignored on non-Makefile
generators.) During a manual build each launcher transparently runs
the command it wraps. During a CTest-driven build for submission to
CDash each launcher reports detailed information when its command
fails or warns. (Setting CTEST_USE_LAUNCHERS in CTestConfig.cmake is
convenient, but also adds the launcher overhead even for manual
builds. One may instead set it in a CTest dashboard script and add it
to the CMake cache for the build tree.)

CTestScriptMode

This file is read by ctest in script mode (-S)

CheckCCompilerFlag
Check whether the C compiler supports a given flag.

CHECK_C_COMPILER_FLAG(<flag> <var>)

<flag> - the compiler flag
<var> - variable to store the result

This internally calls the check_c_source_compiles macro. See help for
CheckCSourceCompiles for a listing of variables that can modify the
build.

CheckCSourceCompiles
Check if given C source compiles and links into an executable

CHECK_C_SOURCE_COMPILES(<code> <var> [FAIL_REGEX <fail-regex>])

the way the check is run:

CheckIncludeFile
macro which checks the include file exists.

CHECK_INCLUDE_FILE(INCLUDE VARIABLE)

STRUCT - the name of the struct or class you are interested in
MEMBER - the member which existence you want to check
HEADER - the header(s) where the prototype should be declared
VARIABLE - variable to store the result

The following variables may be set before calling this macro to modify

CheckSymbolExists
Check if a symbol exists as a function, variable, or macro

CHECK_SYMBOL_EXISTS(<symbol> <files> <variable>)

Check that the <symbol> is available after including given header
<files> and store the result in a <variable>. Specify the list of
files in one argument as a semicolon-separated list.

If the header files define the symbol as a macro it is considered
available and assumed to work. If the header files declare the symbol
as a function or variable then the symbol must also be available for
linking. If the symbol is a type or enum value it will not be
recognized (consider using CheckTypeSize or CheckCSourceCompiles).

The following variables may be set before calling this macro to modify
the way the check is run:

CheckTypeSize
Check sizeof a type

CHECK_TYPE_SIZE(TYPE VARIABLE [BUILTIN_TYPES_ONLY])

Check if the type exists and determine its size. On return,
"HAVE_${VARIABLE}" holds the existence of the type, and "${VARIABLE}"
holds one of the following:

<size> = type has non-zero size <size>
"0" = type has arch-dependent size (see below)
"" = type does not exist

Furthermore, the variable "${VARIABLE}_CODE" holds C preprocessor code
to define the macro "${VARIABLE}" to the size of the type, or leave
the macro undefined if the type does not exist.

The variable "${VARIABLE}" may be "0" when CMAKE_OSX_ARCHITECTURES has
multiple architectures for building OS X universal binaries. This
indicates that the type size varies across architectures. In this
case "${VARIABLE}_CODE" contains C preprocessor tests mapping from
each architecture macro to the corresponding type size. The list of
architecture macros is stored in "${VARIABLE}_KEYS", and the value for
each key is stored in "${VARIABLE}-${KEY}".

If the BUILTIN_TYPES_ONLY option is not given, the macro checks for
headers <sys/types.h>, <stdint.h>, and <stddef.h>, and saves results
in HAVE_SYS_TYPES_H, HAVE_STDINT_H, and HAVE_STDDEF_H. The type size
check automatically includes the available headers, thus supporting
checks of types defined in the headers.

The following variables may be set before calling this macro to modify
the way the check is run:

CheckVariableExists
Check if the variable exists.

CHECK_VARIABLE_EXISTS(VAR VARIABLE)

VAR - the name of the variable
VARIABLE - variable to store the result

This macro is only for C variables.

The following variables may be set before calling this macro to modify
the way the check is run:

CMAKE_REQUIRED_FLAGS = string of compile command line flags
CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
CMAKE_REQUIRED_LIBRARIES = list of libraries to link

Dart
Configure a project for testing with CTest or old Dart Tcl Client

This file is the backwards-compatibility version of the CTest module.
It supports using the old Dart 1 Tcl client for driving dashboard
submissions as well as testing with CTest. This module should be
included in the CMakeLists.txt file at the top of a project. Typical
usage:

INCLUDE(Dart)
IF(BUILD_TESTING)
# ... testing related CMake code ...
ENDIF(BUILD_TESTING)

The BUILD_TESTING option is created by the Dart module to determine
whether testing support should be enabled. The default is ON.

Documentation
DocumentationVTK.cmake

This file provides support for the VTK documentation framework. It
relies on several tools (Doxygen, Perl, etc).

ExternalProject
Create custom targets to build projects in external trees

The 'ExternalProject_Add' function creates a custom target to drive
download, update/patch, configure, build, install and test steps of an
external project:

)

The *_DIR options specify directories for the project, with default
directories computed as follows. If the PREFIX option is given to
ExternalProject_Add() or the EP_PREFIX directory property is set, then
an external project is built and installed under the specified prefix:

TMP_DIR = <prefix>/tmp
STAMP_DIR = <prefix>/src/<name>-stamp
DOWNLOAD_DIR = <prefix>/src
SOURCE_DIR = <prefix>/src/<name>
BINARY_DIR = <prefix>/src/<name>-build
INSTALL_DIR = <prefix>

Otherwise, if the EP_BASE directory property is set then components of
an external project are stored under the specified base:

TMP_DIR = <base>/tmp/<name>
STAMP_DIR = <base>/Stamp/<name>
DOWNLOAD_DIR = <base>/Download/<name>
SOURCE_DIR = <base>/Source/<name>
BINARY_DIR = <base>/Build/<name>
INSTALL_DIR = <base>/Install/<name>

If no PREFIX, EP_PREFIX, or EP_BASE is specified then the default is
to set PREFIX to "<name>-prefix". Relative paths are interpreted with
respect to the build directory corresponding to the source directory
in which ExternalProject_Add is invoked.

If SOURCE_DIR is explicitly set to an existing directory the project
will be built from it. Otherwise a download step must be specified
using one of the DOWNLOAD_COMMAND, CVS_*, SVN_*, or URL options. The
URL option may refer locally to a directory or source tarball, or
refer to a remote tarball (e.g. http://.../src.tgz).

The 'ExternalProject_Add_Step' function adds a custom step to an
external project:

ExternalProject_Add_Step(<name> <step> # Names of project and custom step
[COMMAND cmd...] # Command line invoked by this step
[COMMENT "text..."] # Text printed when step executes
[DEPENDEES steps...] # Steps on which this step depends
[DEPENDERS steps...] # Steps that depend on this step
[DEPENDS files...] # Files on which this step depends
[ALWAYS 1] # No stamp file, step always runs
[WORKING_DIRECTORY dir] # Working directory for command
[LOG 1] # Wrap step in script to log output
)

The command line, comment, and working directory of every standard and
custom step is processed to replace tokens <SOURCE_DIR>, <BINARY_DIR>,
<INSTALL_DIR>, and <TMP_DIR> with corresponding property values.

The 'ExternalProject_Get_Property' function retrieves external project
target properties:

ExternalProject_Get_Property(<name> [prop1 [prop2 [...]]])

It stores property values in variables of the same name. Property
names correspond to the keyword argument names of
'ExternalProject_Add'.

The 'ExternalProject_Add_StepTargets' function generates custom
targets for the steps listed:

ExternalProject_Add_StepTargets(<name> [step1 [step2 [...]]])

If STEP_TARGETS is set then ExternalProject_Add_StepTargets is
automatically called at the end of matching calls to
ExternalProject_Add_Step. Pass STEP_TARGETS explicitly to individual
ExternalProject_Add calls, or implicitly to all ExternalProject_Add
calls by setting the directory property EP_STEP_TARGETS.

If STEP_TARGETS is not set, clients may still manually call
ExternalProject_Add_StepTargets after calling ExternalProject_Add or
ExternalProject_Add_Step.

This functionality is provided to make it easy to drive the steps
independently of each other by specifying targets on build command
lines. For example, you may be submitting to a sub-project based
dashboard, where you want to drive the configure portion of the build,
then submit to the dashboard, followed by the build portion, followed
by tests. If you invoke a custom target that depends on a step
halfway through the step dependency chain, then all the previous steps
will also run to ensure everything is up to date.

For example, to drive configure, build and test steps independently
for each ExternalProject_Add call in your project, write the following
line prior to any ExternalProject_Add calls in your CMakeLists file:

set_property(DIRECTORY PROPERTY EP_STEP_TARGETS configure build test)

FeatureSummary
Macros for generating a summary of enabled/disabled features

This module provides the macros feature_summary(), set_package_info()
and add_feature_info(). For compatiblity it also still provides
set_feature_info(), print_enabled_features() and
print_disabled_features.

These macros can be used to generate a summary of enabled and disabled
packages and/or feature for a build tree:

-- Enabled features:
LibXml2 (required version >= 2.4) , XML processing library. , <http://xmlsoft.org>
PNG , A PNG image library. , <http://www.libpng.org/pub/png/>
-- Disabled features:
Lua51 , The Lua scripting language. , <http://www.lua.org>
Foo , Foo provides cool stuff.

FEATURE_SUMMARY( [FILENAME <file>]
[APPEND]
[VAR <variable_name>]
[DESCRIPTION "Found packages:"]
WHAT (ALL | PACKAGES_FOUND | PACKAGES_NOT_FOUND
| ENABLED_FEATURES | DISABLED_FEATURES]
)

The FEATURE_SUMMARY() macro can be used to print information about
enabled or disabled features or packages of a project. By default,
only the names of the features/packages will be printed and their
required version when one was specified. Use SET_FEATURE_INFO() to
add more useful information, like e.g. a download URL for the
respective package.

The WHAT option is the only mandatory option. Here you specify what
information will be printed:

ENABLED_FEATURES: the list of all features and packages which are enabled,
excluding the QUIET packages
DISABLED_FEATURES: the list of all features and packages which are disabled,
excluding the QUIET packages
PACKAGES_FOUND: the list of all packages which have been found
PACKAGES_NOT_FOUND: the list of all packages which have not been found
ALL: this will give all packages which have or have not been found

If a FILENAME is given, the information is printed into this file. If
APPEND is used, it is appended to this file, otherwise the file is
overwritten if it already existed. If the VAR option is used, the
information is "printed" into the specified variable. If FILENAME is
not used, the information is printed to the terminal. Using the
DESCRIPTION option a description or headline can be set which will be
printed above the actual content.

Example 1, append everything to a file:

feature_summary(WHAT ALL
FILENAME ${CMAKE_BINARY_DIR}/all.log APPEND)

Example 2, print the enabled features into the variable
enabledFeaturesText:

feature_summary(WHAT ENABLED_FEATURES
DESCRIPTION "Enabled Features:"
VAR enabledFeaturesText)
message(STATUS "${enabledFeaturesText}")

SET_PACKAGE_INFO(<name> <description> [<url> [<comment>] ] )

Use this macro to set up information about the named package, which
can then be displayed via FEATURE_SUMMARY(). This can be done either
directly in the Find-module or in the project which uses the module
after the FIND_PACKAGE() call. The features for which information can
be set are added automatically by the find_package() command.

Example for setting the info for a package:

find_package(LibXml2)
set_package_info(LibXml2 "XML processing library." "http://xmlsoft.org/")

ADD_FEATURE_INFO(<name> <enabled> <description>)

Use this macro to add information about a feature with the given
<name>. <enabled> contains whether this feature is enabled or not,
<description> is a text descibing the feature. The information can be
displayed using feature_summary() for ENABLED_FEATURES and
DISABLED_FEATURES respectively.

Example for setting the info for a feature:

option(WITH_FOO "Help for foo" ON)
add_feature_info(Foo WITH_FOO "The Foo feature provides very cool stuff.")

The following macros are provided for compatibility with previous
CMake versions:

PRINT_ENABLED_FEATURES()

Does the same as FEATURE_SUMMARY(WHAT ENABLED_FEATURES DESCRIPTION
"Enabled features:")

PRINT_DISABLED_FEATURES()

Does the same as FEATURE_SUMMARY(WHAT DISABLED_FEATURES DESCRIPTION
"Disabled features:")

SET_FEATURE_INFO(<name> <description> [<url> [<comment>] ] )

Does the same as SET_PACKAGE_INFO(<name> <description> <url> <comment>
)

FindALSA
Find alsa

Find the alsa libraries (asound)

This module defines the following variables:
ALSA_FOUND - True if ALSA_INCLUDE_DIR & ALSA_LIBRARY are found
ALSA_LIBRARIES - Set when ALSA_LIBRARY is found
ALSA_INCLUDE_DIRS - Set when ALSA_INCLUDE_DIR is found

ALSA_INCLUDE_DIR - where to find asoundlib.h, etc.
ALSA_LIBRARY - the asound library

FindASPELL
Try to find ASPELL

Once done this will define

ASPELL_FOUND - system has ASPELL
ASPELL_INCLUDE_DIR - the ASPELL include directory
ASPELL_LIBRARIES - The libraries needed to use ASPELL
ASPELL_DEFINITIONS - Compiler switches required for using ASPELL

FindAVIFile
Locate AVIFILE library and include paths

AVIFILE (http://avifile.sourceforge.net/)is a set of libraries for
i386 machines to use various AVI codecs. Support is limited beyond
Linux. Windows provides native AVI support, and so doesn't need this
library. This module defines

AVIFILE_INCLUDE_DIR, where to find avifile.h , etc.
AVIFILE_LIBRARIES, the libraries to link against
AVIFILE_DEFINITIONS, definitions to use when compiling
AVIFILE_FOUND, If false, don't try to use AVIFILE

FindBISON
Find bison executable and provides macros to generate custom build
rules

The module defines the following variables:

BISON_EXECUTABLE - path to the bison program
BISON_VERSION - version of bison
BISON_FOUND - true if the program was found

The minimum required version of bison can be specified using the
standard CMake syntax, e.g. find_package(BISON 2.1.3)

If bison is found, the module defines the macros:

BISON_TARGET(<Name> <YaccInput> <CodeOutput> [VERBOSE <file>]
[COMPILE_FLAGS <string>])

which will create a custom rule to generate a parser. <YaccInput> is
the path to a yacc file. <CodeOutput> is the name of the source file
generated by bison. A header file is also be generated, and contains
the token list. If COMPILE_FLAGS option is specified, the next
parameter is added in the bison command line. if VERBOSE option is
specified, <file> is created and contains verbose descriptions of the
grammar and parser. The macro defines a set of variables:

BISON_${Name}_DEFINED - true is the macro ran successfully
BISON_${Name}_INPUT - The input source file, an alias for <YaccInput>
BISON_${Name}_OUTPUT_SOURCE - The source file generated by bison
BISON_${Name}_OUTPUT_HEADER - The header file generated by bison
BISON_${Name}_OUTPUTS - The sources files generated by bison
BISON_${Name}_COMPILE_FLAGS - Options used in the bison command line

====================================================================
Example:

find_package(BISON)
BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
add_executable(Foo main.cpp ${BISON_MyParser_OUTPUTS})
====================================================================

FindBLAS
Find BLAS library

This module finds an installed fortran library that implements the
BLAS linear-algebra interface (see http://www.netlib.org/blas/). The
list of libraries searched for is taken from the autoconf macro file,
acx_blas.m4 (distributed at
http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).

This module sets the following variables:

BLAS_FOUND - set to true if a library implementing the BLAS interface
is found
BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
and -L).
BLAS_LIBRARIES - uncached list of libraries (using full path name) to
link against to use BLAS
BLAS95_LIBRARIES - uncached list of libraries (using full path name)
to link against to use BLAS95 interface
BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
is found
BLA_STATIC if set on this determines what kind of linkage we do (static)
BLA_VENDOR if set checks only the specified vendor, if not set checks
all the possibilities
BLA_F95 if set on tries to find the f95 interfaces for BLAS/LAPACK

######### ## List of vendors (BLA_VENDOR) valid in this module #
ATLAS, PhiPACK,CXML,DXML,SunPerf,SCSL,SGIMATH,IBMESSL,Intel10_32
(intel mkl v10 32 bit),Intel10_64lp (intel mkl v10 64 bit,lp thread
model, lp64 model), # Intel( older versions of mkl 32 and 64 bit),
ACML,Apple, NAS, Generic C/CXX should be enabled to use Intel mkl

FindBZip2
Try to find BZip2

Once done this will define

BZIP2_FOUND - system has BZip2
BZIP2_INCLUDE_DIR - the BZip2 include directory
BZIP2_LIBRARIES - Link these to use BZip2
BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_

FindBoost
Try to find Boost include dirs and libraries

Usage of this module as follows:

NOTE: Take note of the Boost_ADDITIONAL_VERSIONS variable below. Due
to Boost naming conventions and limitations in CMake this find module
is NOT future safe with respect to Boost version numbers, and may
break.

== Using Header-Only libraries from within Boost: ==

find_package( Boost 1.36.0 )
if(Boost_FOUND)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(foo foo.cc)
endif()

== Using actual libraries from within Boost: ==

set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
find_package( Boost 1.36.0 COMPONENTS date_time filesystem system ... )

if(Boost_FOUND)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(foo foo.cc)
target_link_libraries(foo ${Boost_LIBRARIES})
endif()

The components list needs to contain actual names of boost libraries
only, such as "date_time" for "libboost_date_time". If you're using
parts of Boost that contain header files only (e.g. foreach) you do
not need to specify COMPONENTS.

You should provide a minimum version number that should be used. If
you provide this version number and specify the REQUIRED attribute,
this module will fail if it can't find the specified or a later
version. If you specify a version number this is automatically put
into the considered list of version numbers and thus doesn't need to
be specified in the Boost_ADDITIONAL_VERSIONS variable (see below).

NOTE for Visual Studio Users:

Automatic linking is used on MSVC & Borland compilers by default when
#including things in Boost. It's important to note that setting
Boost_USE_STATIC_LIBS to OFF is NOT enough to get you dynamic linking,
should you need this feature. Automatic linking typically uses static
libraries with a few exceptions (Boost.Python is one).

Please see the section below near Boost_LIB_DIAGNOSTIC_DEFINITIONS for
more details. Adding a TARGET_LINK_LIBRARIES() as shown in the example
above appears to cause VS to link dynamically if Boost_USE_STATIC_LIBS
gets set to OFF. It is suggested you avoid automatic linking since it
will make your application less portable.

=========== The mess that is Boost_ADDITIONAL_VERSIONS (sorry?)
============

OK, so the Boost_ADDITIONAL_VERSIONS variable can be used to specify a
list of boost version numbers that should be taken into account when
searching for Boost. Unfortunately boost puts the version number into
the actual filename for the libraries, so this variable will certainly
be needed in the future when new Boost versions are released.

Currently this module searches for the following version numbers:
1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1, 1.35, 1.35.0, 1.35.1,
1.36, 1.36.0, 1.36.1, 1.37, 1.37.0, 1.38, 1.38.0, 1.39, 1.39.0, 1.40,
1.40.0, 1.41, 1.41.0, 1.42, 1.42.0, 1.43, 1.43.0, 1.44, 1.44.0, 1.45,
1.45.0, 1.46, 1.46.0

NOTE: If you add a new major 1.x version in Boost_ADDITIONAL_VERSIONS
you should add both 1.x and 1.x.0 as shown above. Official Boost
include directories omit the 3rd version number from include paths if
it is 0 although not all binary Boost releases do so.

set(Boost_ADDITIONAL_VERSIONS "1.78" "1.78.0" "1.79" "1.79.0")

===================================== =============
========================

Variables used by this module, they can change the default behaviour
and need to be set before calling find_package:

Boost_USE_MULTITHREADED Can be set to OFF to use the non-multithreaded
boost libraries. If not specified, defaults
to ON.

Boost_USE_STATIC_LIBS Can be set to ON to force the use of the static
boost libraries. Defaults to OFF.

Boost_NO_SYSTEM_PATHS Set to TRUE to suppress searching in system
paths (or other locations outside of BOOST_ROOT
or BOOST_INCLUDEDIR). Useful when specifying
BOOST_ROOT. Defaults to OFF.
[Since CMake 2.8.3]

Boost_USE_STATIC_RUNTIME If enabled, searches for boost libraries
linked against a static C++ standard library
('s' ABI tag). This option should be set to
ON or OFF because the default behavior
if not specified is platform dependent
for backwards compatibility.
[Since CMake 2.8.3]

Boost_USE_DEBUG_PYTHON If enabled, searches for boost libraries
compiled against a special debug build of
Python ('y' ABI tag). Defaults to OFF.
[Since CMake 2.8.3]

Boost_USE_STLPORT If enabled, searches for boost libraries
compiled against the STLPort standard
library ('p' ABI tag). Defaults to OFF.
[Since CMake 2.8.3]

Boost_USE_STLPORT_DEPRECATED_NATIVE_IOSTREAMS
If enabled, searches for boost libraries
compiled against the deprecated STLPort
"native iostreams" feature ('n' ABI tag).
Defaults to OFF.
[Since CMake 2.8.3]

Other Variables used by this module which you may want to set.

Boost_ADDITIONAL_VERSIONS A list of version numbers to use for searching
the boost include directory. Please see
the documentation above regarding this
annoying, but necessary variable :(

Boost_DEBUG Set this to TRUE to enable debugging output
of FindBoost.cmake if you are having problems.
Please enable this before filing any bug
reports.

Boost_DETAILED_FAILURE_MSG FindBoost doesn't output detailed information
about why it failed or how to fix the problem
unless this is set to TRUE or the REQUIRED
keyword is specified in find_package().
[Since CMake 2.8.0]

Boost_COMPILER Set this to the compiler suffix used by Boost
(e.g. "-gcc43") if FindBoost has problems finding
the proper Boost installation

Boost_THREADAPI When building boost.thread, sometimes the name of the
library contains an additional "pthread" or "win32"
string known as the threadapi. This can happen when
compiling against pthreads on Windows or win32 threads
on Cygwin. You may specify this variable and if set
when FindBoost searches for the Boost threading library
it will first try to match the threadapi you specify.
For Example: libboost_thread_win32-mgw45-mt-1_43.a
might be found if you specified "win32" here before
falling back on libboost_thread-mgw45-mt-1_43.a.
[Since CMake 2.8.3]

Boost_REALPATH Resolves symbolic links for discovered boost libraries
to assist with packaging. For example, instead of
Boost_SYSTEM_LIBRARY_RELEASE being resolved to
"/usr/lib/libboost_system.so" it would be
"/usr/lib/libboost_system.so.1.42.0" instead.
This does not affect linking and should not be
enabled unless the user needs this information.
[Since CMake 2.8.3]

FindBullet
Try to find the Bullet physics engine

This module defines the following variables

BULLET_FOUND - Was bullet found
BULLET_INCLUDE_DIRS - the Bullet include directories
BULLET_LIBRARIES - Link to this, by default it includes
all bullet components (Dynamics,
Collision, LinearMath, & SoftBody)

This module accepts the following variables

BULLET_ROOT - Can be set to bullet install path or Windows build path

FindCABLE
Find CABLE

This module finds if CABLE is installed and determines where the
include files and libraries are. This code sets the following
variables:

CABLE the path to the cable executable
CABLE_TCL_LIBRARY the path to the Tcl wrapper library
CABLE_INCLUDE_DIR the path to the include directory

To build Tcl wrappers, you should add shared library and link it to
${CABLE_TCL_LIBRARY}. You should also add ${CABLE_INCLUDE_DIR} as an
include directory.

FindCUDA
Tools for building CUDA C files: libraries and build dependencies.

This script locates the NVIDIA CUDA C tools. It should work on linux,
windows, and mac and should be reasonably up to date with CUDA C
releases.

This script makes use of the standard find_package arguments of
<VERSION>, REQUIRED and QUIET. CUDA_FOUND will report if an
acceptable version of CUDA was found.

The script will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR if
the prefix cannot be determined by the location of nvcc in the system
path and REQUIRED is specified to find_package(). To use a different
installed version of the toolkit set the environment variable
CUDA_BIN_PATH before running cmake (e.g.
CUDA_BIN_PATH=/usr/local/cuda1.0 instead of the default
/usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring. If
you change the value of CUDA_TOOLKIT_ROOT_DIR, various components that
depend on the path will be relocated.

It might be necessary to set CUDA_TOOLKIT_ROOT_DIR manually on certain
platforms, or to use a cuda runtime not installed in the default
location. In newer versions of the toolkit the cuda library is
included with the graphics driver- be sure that the driver version
matches what is needed by the cuda runtime version.

The following variables affect the behavior of the macros in the
script (in alphebetical order). Note that any of these flags can be
changed multiple times in the same directory before calling
CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY, CUDA_COMPILE, CUDA_COMPILE_PTX
or CUDA_WRAP_SRCS.

CUDA_64_BIT_DEVICE_CODE (Default matches host bit size)
-- Set to ON to compile for 64 bit device code, OFF for 32 bit device code.
Note that making this different from the host code when generating object
or C files from CUDA code just won't work, because size_t gets defined by
nvcc in the generated source. If you compile to PTX and then load the
file yourself, you can mix bit sizes between device and host.

CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON)
-- Set to ON if you want the custom build rule to be attached to the source
file in Visual Studio. Turn OFF if you add the same cuda file to multiple
targets.

This allows the user to build the target from the CUDA file; however, bad
things can happen if the CUDA source file is added to multiple targets.
When performing parallel builds it is possible for the custom build
command to be run more than once and in parallel causing cryptic build
errors. VS runs the rules for every source file in the target, and a
source can have only one rule no matter how many projects it is added to.
When the rule is run from multiple targets race conditions can occur on
the generated file. Eventually everything will get built, but if the user
is unaware of this behavior, there may be confusion. It would be nice if
this script could detect the reuse of source files across multiple targets
and turn the option off for the user, but no good solution could be found.

CUDA_BUILD_CUBIN (Default OFF)
-- Set to ON to enable and extra compilation pass with the -cubin option in
Device mode. The output is parsed and register, shared memory usage is
printed during build.

CUDA_BUILD_EMULATION (Default OFF for device mode)
-- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files
when CUDA_BUILD_EMULATION is TRUE.

CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR)
-- Set to the path you wish to have the generated files placed. If it is
blank output files will be placed in CMAKE_CURRENT_BINARY_DIR.
Intermediate files will always be placed in
CMAKE_CURRENT_BINARY_DIR/CMakeFiles.

CUDA_HOST_COMPILATION_CPP (Default ON)
-- Set to OFF for C compilation of host code.

CUDA_NVCC_FLAGS
CUDA_NVCC_FLAGS_<CONFIG>
-- Additional NVCC command line arguments. NOTE: multiple arguments must be
semi-colon delimited (e.g. --compiler-options;-Wall)

CUDA_PROPAGATE_HOST_FLAGS (Default ON)
-- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration
dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the
host compiler through nvcc's -Xcompiler flag. This helps make the
generated host code match the rest of the system better. Sometimes
certain flags give nvcc problems, and this will help you turn the flag
propagation off. This does not affect the flags supplied directly to nvcc
via CUDA_NVCC_FLAGS or through the OPTION flags specified through
CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS. Flags used for
shared library compilation are not affected by this flag.

CUDA_VERBOSE_BUILD (Default OFF)
-- Set to ON to see all the commands used when building the CUDA file. When
using a Makefile generator the value defaults to VERBOSE (run make
VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will
always print the output.

The script creates the following macros (in alphebetical order):

CUDA_ADD_CUFFT_TO_TARGET( cuda_target )
-- Adds the cufft library to the target (can be any target). Handles whether
you are in emulation mode or not.

CUDA_ADD_CUBLAS_TO_TARGET( cuda_target )
-- Adds the cublas library to the target (can be any target). Handles
whether you are in emulation mode or not.

CUDA_ADD_EXECUTABLE( cuda_target file0 file1 ...
[WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
-- Creates an executable "cuda_target" which is made up of the files
specified. All of the non CUDA C files are compiled using the standard
build rules specified by CMAKE and the cuda files are compiled to object
files using nvcc and the host compiler. In addition CUDA_INCLUDE_DIRS is
added automatically to include_directories(). Some standard CMake target
calls can be used on the target after calling this macro
(e.g. set_target_properties and target_link_libraries), but setting
properties that adjust compilation flags will not affect code compiled by
nvcc. Such flags should be modified before calling CUDA_ADD_EXECUTABLE,
CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS.

CUDA_ADD_LIBRARY( cuda_target file0 file1 ...
[STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
-- Same as CUDA_ADD_EXECUTABLE except that a library is created.

CUDA_BUILD_CLEAN_TARGET()
-- Creates a convience target that deletes all the dependency files
generated. You should make clean after running this target to ensure the
dependency files get regenerated.

CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE]
[OPTIONS ...] )
-- Returns a list of generated files from the input source files to be used
with ADD_LIBRARY or ADD_EXECUTABLE.

CUDA_COMPILE_PTX( generated_files file0 file1 ... [OPTIONS ...] )
-- Returns a list of PTX files generated from the input source files.

CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )
-- Sets the directories that should be passed to nvcc
(e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu
files.

CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...
[STATIC | SHARED | MODULE] [OPTIONS ...] )
-- This is where all the magic happens. CUDA_ADD_EXECUTABLE,
CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this
function under the hood.

Given the list of files (file0 file1 ... fileN) this macro generates
custom commands that generate either PTX or linkable objects (use "PTX" or
"OBJ" for the format argument to switch). Files that don't end with .cu
or have the HEADER_FILE_ONLY property are ignored.

The arguments passed in after OPTIONS are extra command line options to
give to nvcc. You can also specify per configuration options by
specifying the name of the configuration followed by the options. General
options must preceed configuration specific options. Not all
configurations need to be specified, only the ones provided will be used.

OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag"
DEBUG -g
RELEASE --use_fast_math
RELWITHDEBINFO --use_fast_math;-g
MINSIZEREL --use_fast_math

For certain configurations (namely VS generating object files with
CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will
be produced for the given cuda file. This is because when you add the
cuda file to Visual Studio it knows that this file produces an object file
and will link in the resulting object file automatically.

This script will also generate a separate cmake script that is used at
build time to invoke nvcc. This is for several reasons.

1. nvcc can return negative numbers as return values which confuses
Visual Studio into thinking that the command succeeded. The script now
checks the error codes and produces errors when there was a problem.

2. nvcc has been known to not delete incomplete results when it
encounters problems. This confuses build systems into thinking the
target was generated when in fact an unusable file exists. The script
now deletes the output files if there was an error.

3. By putting all the options that affect the build into a file and then
make the build rule dependent on the file, the output files will be
regenerated when the options change.

This script also looks at optional arguments STATIC, SHARED, or MODULE to
determine when to target the object compilation for a shared library.
BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in
CUDA_ADD_LIBRARY. On some systems special flags are added for building
objects intended for shared libraries. A preprocessor macro,
<target_name>_EXPORTS is defined when a shared library compilation is
detected.

Flags passed into add_definitions with -D or /D are passed along to nvcc.

The script defines the following variables:

CUDA_VERSION_MAJOR -- The major version of cuda as reported by nvcc.
CUDA_VERSION_MINOR -- The minor version.
CUDA_VERSION
CUDA_VERSION_STRING -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR

CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set).
CUDA_SDK_ROOT_DIR -- Path to the CUDA SDK. Use this to find files in the
SDK. This script will not directly support finding
specific libraries or headers, as that isn't
supported by NVIDIA. If you want to change
libraries when the path changes see the
FindCUDA.cmake script for an example of how to clear
these variables. There are also examples of how to
use the CUDA_SDK_ROOT_DIR to locate headers or
libraries, if you so choose (at your own risk).
CUDA_INCLUDE_DIRS -- Include directory for cuda headers. Added automatically
for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY.
CUDA_LIBRARIES -- Cuda RT library.
CUDA_CUFFT_LIBRARIES -- Device or emulation library for the Cuda FFT
implementation (alternative to:
CUDA_ADD_CUFFT_TO_TARGET macro)
CUDA_CUBLAS_LIBRARIES -- Device or emulation library for the Cuda BLAS
implementation (alterative to:
CUDA_ADD_CUBLAS_TO_TARGET macro).

INPUT Variables

CXXTEST_USE_PYTHON [deprecated since 1.3]
Only used in the case both Python & Perl
are detected on the system to control
which CxxTest code generator is used.

NOTE: In older versions of this Find Module,
this variable controlled if the Python test
generator was used instead of the Perl one,
regardless of which scripting language the
user had installed.

CXXTEST_TESTGEN_ARGS (since CMake 2.8.3)
Specify a list of options to pass to the CxxTest code
generator. If not defined, --error-printer is
passed.

enable_testing()

CXXTEST_ADD_TEST(unittest_foo foo_test.cc
${CMAKE_CURRENT_SOURCE_DIR}/foo_test.h)
target_link_libraries(unittest_foo foo) # as needed
endif()

This will (if CxxTest is found):
1. Invoke the testgen executable to autogenerate foo_test.cc in the
binary tree from "foo_test.h" in the current source directory.
2. Create an executable and test called unittest_foo.

#=============
Example foo_test.h:

#include <cxxtest/TestSuite.h>

class MyTestSuite : public CxxTest::TestSuite
{
public:
void testAddition( void )
{
TS_ASSERT( 1 + 1 > 1 );
TS_ASSERT_EQUALS( 1 + 1, 2 );
}
};

point to where it found it.

FindDevIL

This module locates the developer's image library.
http://openil.sourceforge.net/

This module sets: IL_LIBRARIES the name of the IL library. These
include the full path to the core DevIL library. This one has to be
linked into the application. ILU_LIBRARIES the name of the ILU
library. Again, the full path. This library is for filters and
effects, not actual loading. It doesn't have to be linked if the
functionality it provides is not used. ILUT_LIBRARIES the name of the
ILUT library. Full path. This part of the library interfaces with
OpenGL. It is not strictly needed in applications. IL_INCLUDE_DIR
where to find the il.h, ilu.h and ilut.h files. IL_FOUND this is set
to TRUE if all the above variables were set. This will be set to
false if ILU or ILUT are not found, even if they are not needed. In
most systems, if one library is found all the others are as well.
That's the way the DevIL developers release it.

FindDoxygen
This module looks for Doxygen and the path to Graphviz's dot

Doxygen is a documentation generation tool. Please see

FindFLEX
Find flex executable and provides a macro to generate custom build
rules

The module defines the following variables:

FLEX_FOUND - true is flex executable is found

FLEX_VERSION - the version of flex
FLEX_LIBRARIES - The flex libraries

The minimum required version of flex can be specified using the
standard syntax, e.g. FIND_PACKAGE(FLEX 2.5.13)

If flex is found on the system, the module provides the macro:

FLEX_TARGET(Name FlexInput FlexOutput [COMPILE_FLAGS <string>])

which creates a custom command to generate the <FlexOutput> file from
the <FlexInput> file. If COMPILE_FLAGS option is specified, the next
parameter is added to the flex command line. Name is an alias used to
get details of this custom command. Indeed the macro defines the
following variables:

FLEX_${Name}_DEFINED - true is the macro ran successfully
FLEX_${Name}_OUTPUTS - the source file generated by the custom rule, an
alias for FlexOutput
FLEX_${Name}_INPUT - the flex source file, an alias for ${FlexInput}

Flex scanners oftenly use tokens defined by Bison: the code generated
by Flex depends of the header generated by Bison. This module also
defines a macro:

ADD_FLEX_BISON_DEPENDENCY(FlexTarget BisonTarget)

which adds the required dependency between a scanner and a parser
where <FlexTarget> and <BisonTarget> are the first parameters of
respectively FLEX_TARGET and BISON_TARGET macros.

====================================================================
Example:

find_package(BISON)
find_package(FLEX)

BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
FLEX_TARGET(MyScanner lexer.l ${CMAKE_CURRENT_BINARY_DIR}/lexer.cpp)
ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)

FindHDF5
Find HDF5, a library for reading and writing self describing array
data.

This module invokes the HDF5 wrapper compiler that should be installed
alongside HDF5. Depending upon the HDF5 Configuration, the wrapper
compiler is called either h5cc or h5pcc. If this succeeds, the module
will then call the compiler with the -show argument to see what flags
are used when compiling an HDF5 client application.

The module will optionally accept the COMPONENTS argument. If no
COMPONENTS are specified, then the find module will default to finding
only the HDF5 C library. If one or more COMPONENTS are specified, the
module will attempt to find the language bindings for the specified
components. Currently, the only valid components are C and CXX. The
module does not yet support finding the Fortran bindings. If the
COMPONENTS argument is not given, the module will attempt to find only
the C bindings.

On UNIX systems, this module will read the variable
HDF5_USE_STATIC_LIBRARIES to determine whether or not to prefer a
static link to a dynamic link for HDF5 and all of it's dependencies.
To use this feature, make sure that the HDF5_USE_STATIC_LIBRARIES
variable is set before the call to find_package.

To provide the module with a hint about where to find your HDF5
installation, you can set the environment variable HDF5_ROOT. The
Find module will then look in this path when searching for HDF5
executables, paths, and libraries.

In addition to finding the includes and libraries required to compile
an HDF5 client application, this module also makes an effort to find
tools that come with the HDF5 distribution that may be useful for
regression testing.

This module will define the following variables:

HDF5_INCLUDE_DIRS - Location of the hdf5 includes
HDF5_INCLUDE_DIR - Location of the hdf5 includes (deprecated)
HDF5_DEFINITIONS - Required compiler definitions for HDF5
HDF5_C_LIBRARIES - Required libraries for the HDF5 C bindings.

FindMPI
Message Passing Interface (MPI) module.

The Message Passing Interface (MPI) is a library used to write
high-performance parallel applications that use message passing, and
is typically deployed on a cluster. MPI is a standard interface
(defined by the MPI forum) for which many implementations are
available. All of these implementations have somewhat different
compilation approaches (different include paths, libraries to link
against, etc.), and this module tries to smooth out those differences.

This module will set the following variables:

MPI_FOUND TRUE if we have found MPI
MPI_COMPILE_FLAGS Compilation flags for MPI programs
MPI_INCLUDE_PATH Include path(s) for MPI header
MPI_LINK_FLAGS Linking flags for MPI programs
MPI_LIBRARY First MPI library to link against (cached)
MPI_EXTRA_LIBRARY Extra MPI libraries to link against (cached)
MPI_LIBRARIES All libraries to link MPI programs against
MPIEXEC Executable for running MPI programs
MPIEXEC_NUMPROC_FLAG Flag to pass to MPIEXEC before giving it the
number of processors to run on
MPIEXEC_PREFLAGS Flags to pass to MPIEXEC directly before the
executable to run.
MPIEXEC_POSTFLAGS Flags to pass to MPIEXEC after all other flags.

This module will attempt to auto-detect these settings, first by
looking for a MPI compiler, which many MPI implementations provide as
a pass-through to the native compiler to simplify the compilation of
MPI programs. The MPI compiler is stored in the cache variable
MPI_COMPILER, and will attempt to look for commonly-named drivers
mpic++, mpicxx, mpiCC, or mpicc. If the compiler driver is found and
recognized, it will be used to set all of the module variables. To
skip this auto-detection, set MPI_LIBRARY and MPI_INCLUDE_PATH in the
CMake cache.

If no compiler driver is found or the compiler driver is not
recognized, this module will then search for common include paths and
library names to try to detect MPI.

If CMake initially finds a different MPI than was intended, and you
want to use the MPI compiler auto-detection for a different MPI
implementation, set MPI_COMPILER to the MPI compiler driver you want
to use (e.g., mpicxx) and then set MPI_LIBRARY to the string
MPI_LIBRARY-NOTFOUND. When you re-configure, auto-detection of MPI
will run again with the newly-specified MPI_COMPILER.

When using MPIEXEC to execute MPI applications, you should typically
use all of the MPIEXEC flags as follows:

${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS ${MPIEXEC_PREFLAGS} EXECUTABLE
${MPIEXEC_POSTFLAGS} ARGS

where PROCS is the number of processors on which to execute the
program, EXECUTABLE is the MPI program, and ARGS are the arguments to
pass to the MPI program.

OPENGL_LIBRARIES - Link these to use OpenGL and GLU

If you want to use just GL you can use these values

OPENGL_gl_LIBRARY - Path to OpenGL Library
OPENGL_glu_LIBRARY - Path to GLU Library

On OSX default to using the framework version of opengl People will
have to change the cache values of OPENGL_glu_LIBRARY and
OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX

FindOpenMP
Finds OpenMP support

This module can be used to detect OpenMP support in a compiler. If
the compiler supports OpenMP, the flags required to compile with
openmp support are set.

The following variables are set:

OpenMP_C_FLAGS - flags to add to the C compiler for OpenMP support
OpenMP_CXX_FLAGS - flags to add to the CXX compiler for OpenMP support
OPENMP_FOUND - true if openmp is detected

Supported compilers can be found at
http://openmp.org/wp/openmp-compilers/

FindOpenSSL
Try to find the OpenSSL encryption library

Once done this will define

OPENSSL_ROOT_DIR - Set this variable to the root installation of OpenSSL

Read-Only variables:

OPENSSL_FOUND - system has the OpenSSL library
OPENSSL_INCLUDE_DIR - the OpenSSL include directory
OPENSSL_LIBRARIES - The libraries needed to use OpenSSL

FindOpenSceneGraph
Find OpenSceneGraph

This module searches for the OpenSceneGraph core "osg" library as well
as OpenThreads, and whatever additional COMPONENTS (nodekits) that you
specify.

See http://www.openscenegraph.org

NOTE: To use this module effectively you must either require CMake >=
2.6.3 with cmake_minimum_required(VERSION 2.6.3) or download and place
FindOpenThreads.cmake, Findosg_functions.cmake, Findosg.cmake, and
Find<etc>.cmake files into your CMAKE_MODULE_PATH.

==================================

This module accepts the following variables (note mixed case)

OpenSceneGraph_DEBUG - Enable debugging output

OpenSceneGraph_MARK_AS_ADVANCED - Mark cache variables as advanced
automatically

The following environment variables are also respected for finding the
OSG and it's various components. CMAKE_PREFIX_PATH can also be used
for this (see find_library() CMake documentation).

<MODULE>_DIR (where MODULE is of the form "OSGVOLUME" and there is a FindosgVolume.cmake file)
OSG_DIR
OSGDIR
OSG_ROOT

This module defines the following output variables:

OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found?

OPENSCENEGRAPH_VERSION - The version of the OSG which was found

OPENSCENEGRAPH_INCLUDE_DIRS - Where to find the headers

OPENSCENEGRAPH_LIBRARIES - The OSG libraries

================================== Example Usage:

find_package(OpenSceneGraph 2.0.0 REQUIRED osgDB osgUtil)
# libOpenThreads & libosg automatically searched
include_directories(${OPENSCENEGRAPH_INCLUDE_DIRS})

add_executable(foo foo.cc)
target_link_libraries(foo ${OPENSCENEGRAPH_LIBRARIES})

FindOpenThreads

OpenThreads is a C++ based threading library. Its largest userbase
seems to OpenSceneGraph so you might notice I accept OSGDIR as an
environment path. I consider this part of the Findosg* suite used to
find OpenSceneGraph components. Each component is separate and you
must opt in to each module.

Locate OpenThreads This module defines OPENTHREADS_LIBRARY
OPENTHREADS_FOUND, if false, do not try to link to OpenThreads
OPENTHREADS_INCLUDE_DIR, where to find the headers

$OPENTHREADS_DIR is an environment variable that would correspond to
the ./configure --prefix=$OPENTHREADS_DIR used in building osg.

PHP4_INCLUDE_PATH = path to where php.h can be found
PHP4_EXECUTABLE = full path to the php4 binary

FindPNG
Find the native PNG includes and library

This module defines

PNG_INCLUDE_DIR, where to find png.h, etc.
PNG_LIBRARIES, the libraries to link against to use PNG.
PNG_DEFINITIONS - You should add_definitons(${PNG_DEFINITIONS}) before compiling code that includes png library files.
PNG_FOUND, If false, do not try to use PNG.

also defined, but not for general use are

PNG_LIBRARY, where to find the PNG library.

None of the above will be defined unles zlib can be found. PNG
depends on Zlib

FindPackageHandleStandardArgs

FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> ... )

This function is intended to be used in FindXXX.cmake modules files.
It handles the REQUIRED, QUIET and version-related arguments to
FIND_PACKAGE(). It also sets the <UPPERCASED_NAME>_FOUND variable.
The package is considered found if all variables <var1>... listed
contain valid results, e.g. valid filepaths.

There are two modes of this function. The first argument in both
modes is the name of the Find-module where it is called (in original
casing).

The first simple mode looks like this:

FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> (DEFAULT_MSG|"Custom failure message") <var1>...<varN> )

If the variables <var1> to <varN> are all valid, then
<UPPERCASED_NAME>_FOUND will be set to TRUE. If DEFAULT_MSG is given
as second argument, then the function will generate itself useful
success and error messages. You can also supply a custom error
message for the failure case. This is not recommended.

The second mode is more powerful and also supports version checking:

FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME [REQUIRED_VARS <var1>...<varN>]
[VERSION_VAR <versionvar>
[CONFIG_MODE]
[FAIL_MESSAGE "Custom failure message"] )

As above, if <var1> through <varN> are all valid,
<UPPERCASED_NAME>_FOUND will be set to TRUE. After REQUIRED_VARS the
variables which are required for this package are listed. Following
VERSION_VAR the name of the variable can be specified which holds the
version of the package which has been found. If this is done, this
version will be checked against the (potentially) specified required
version used in the find_package() call. The EXACT keyword is also
handled. The default messages include information about the required
version and the version which has been actually found, both if the
version is ok or not. Use the option CONFIG_MODE if your
FindXXX.cmake module is a wrapper for a find_package(... NO_MODULE)
call, in this case all the information provided by the config-mode of
find_package() will be evaluated automatically. Via FAIL_MESSAGE a
custom failure message can be specified, if this is not used, the
default message will be displayed.

Example for mode 1:

FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)

LibXml2 is considered to be found, if both LIBXML2_LIBRARY and
LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to
TRUE. If it is not found and REQUIRED was used, it fails with
FATAL_ERROR, independent whether QUIET was used or not. If it is
found, success will be reported, including the content of <var1>. On
repeated Cmake runs, the same message won't be printed again.

Example for mode 2:

FIND_PACKAGE_HANDLE_STANDARD_ARGS(BISON REQUIRED_VARS BISON_EXECUTABLE
VERSION_VAR BISON_VERSION)

In this case, BISON is considered to be found if the variable(s)
listed after REQUIRED_VAR are all valid, i.e. BISON_EXECUTABLE in
this case. Also the version of BISON will be checked by using the
version contained in BISON_VERSION. Since no FAIL_MESSAGE is given,
the default messages will be printed.

Another example for mode 2:

FIND_PACKAGE(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
FIND_PACKAGE_HANDLE_STANDARD_ARGS(Automoc4 CONFIG_MODE)

In this case, FindAutmoc4.cmake wraps a call to FIND_PACKAGE(Automoc4
NO_MODULE) and adds an additional search directory for automoc4. The
following FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper
success/error message.

FindPackageMessage

FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")

This macro is intended to be used in FindXXX.cmake modules files. It
will print a message once for each unique find result. This is useful
for telling the user where a package was found. The first argument
specifies the name (XXX) of the package. The second argument
specifies the message to display. The third argument lists details
about the find result so that if they change the message will be
displayed again. The macro also obeys the QUIET argument to the
find_package command.

Example:

IF(X11_FOUND)
FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
"[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
ELSE(X11_FOUND)
...
ENDIF(X11_FOUND)

FindPerl
Find perl

this module looks for Perl

PERL_EXECUTABLE - the full path to perl
PERL_FOUND - If false, don't attempt to use perl.

FindPerlLibs
Find Perl libraries

This module finds if PERL is installed and determines where the
include files and libraries are. It also determines what the name of
the library is. This code sets the following variables:

PERLLIBS_FOUND = True if perl.h & libperl were found
PERL_INCLUDE_PATH = path to where perl.h is found
PERL_LIBRARY = path to libperl
PERL_EXECUTABLE = full path to the perl binary

The minimum required version of Perl can be specified using the
standard syntax, e.g. FIND_PACKAGE(PerlLibs 6.0)

The following variables are also available if needed
(introduced after CMake 2.6.4)

PERL_SITESEARCH = path to the sitesearch install dir
PERL_SITELIB = path to the sitelib install directory
PERL_VENDORARCH = path to the vendor arch install directory
PERL_VENDORLIB = path to the vendor lib install directory
PERL_ARCHLIB = path to the arch lib install directory
PERL_PRIVLIB = path to the priv lib install directory
PERL_EXTRA_C_FLAGS = Compilation flags used to build perl

FindPhysFS

Locate PhysFS library This module defines PHYSFS_LIBRARY, the name of
the library to link against PHYSFS_FOUND, if false, do not try to link
to PHYSFS PHYSFS_INCLUDE_DIR, where to find physfs.h

$PHYSFSDIR is an environment variable that would correspond to the
./configure --prefix=$PHYSFSDIR used in building PHYSFS.

Created by Eric Wing.

FindPike
Find Pike

This module finds if PIKE is installed and determines where the
include files and libraries are. It also determines what the name of
the library is. This code sets the following variables:

PIKE_INCLUDE_PATH = path to where program.h is found
PIKE_EXECUTABLE = full path to the pike binary

FindPkgConfig
a pkg-config module for CMake

Usage:

pkg_check_modules(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*)
checks for all the given modules

pkg_search_module(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*)
checks for given modules and uses the first working one

When the 'REQUIRED' argument was set, macros will fail with an error
when module(s) could not be found

When the 'QUIET' argument is set, no status messages will be printed.

It sets the following variables:

PKG_CONFIG_FOUND ... true if pkg-config works on the system
PKG_CONFIG_EXECUTABLE ... pathname of the pkg-config program
<PREFIX>_FOUND ... set to 1 if module(s) exist

For the following variables two sets of values exist; first one is the
common one and has the given PREFIX. The second set contains flags
which are given out when pkgconfig was called with the '--static'
option.

<XPREFIX>_LIBRARIES ... only the libraries (w/o the '-l')
<XPREFIX>_LIBRARY_DIRS ... the paths of the libraries (w/o the '-L')
<XPREFIX>_LDFLAGS ... all required linker flags
<XPREFIX>_LDFLAGS_OTHER ... all other linker flags
<XPREFIX>_INCLUDE_DIRS ... the '-I' preprocessor flags (w/o the '-I')
<XPREFIX>_CFLAGS ... all required cflags
<XPREFIX>_CFLAGS_OTHER ... the other compiler flags

<XPREFIX> = <PREFIX> for common case
<XPREFIX> = <PREFIX>_STATIC for static linking

There are some special variables whose prefix depends on the count of
given modules. When there is only one module, <PREFIX> stays
unchanged. When there are multiple modules, the prefix will be
changed to <PREFIX>_<MODNAME>:

<XPREFIX>_VERSION ... version of the module
<XPREFIX>_PREFIX ... prefix-directory of the module
<XPREFIX>_INCLUDEDIR ... include-dir of the module
<XPREFIX>_LIBDIR ... lib-dir of the module

<XPREFIX> = <PREFIX> when |MODULES| == 1, else
<XPREFIX> = <PREFIX>_<MODNAME>

A <MODULE> parameter can have the following formats:

{MODNAME} ... matches any version
{MODNAME}>={VERSION} ... at least version <VERSION> is required
{MODNAME}={VERSION} ... exactly version <VERSION> is required
{MODNAME}<={VERSION} ... modules must not be newer than <VERSION>

Examples

pkg_check_modules (GLIB2 glib-2.0)

pkg_check_modules (GLIB2 glib-2.0>=2.10)
requires at least version 2.10 of glib2 and defines e.g.
GLIB2_VERSION=2.10.3

pkg_check_modules (FOO glib-2.0>=2.10 gtk+-2.0)
requires both glib2 and gtk2, and defines e.g.
FOO_glib-2.0_VERSION=2.10.3
FOO_gtk+-2.0_VERSION=2.8.20

pkg_check_modules (XRENDER REQUIRED xrender)
defines e.g.:
XRENDER_LIBRARIES=Xrender;X11
XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp

pkg_search_module (BAR libxml-2.0 libxml2 libxml>=2)

FindPostgreSQL

--------------------------------------------------------------------------

Find the PostgreSQL installation.

Usage: In your CMakeLists.txt file do something like this: ... #
PostgreSQL FIND_PACKAGE(PostgreSQL) ... if( PostgreSQL_FOUND )

include_directories(${PostgreSQL_INCLUDE_DIRS})
link_directories(${PostgreSQL_LIBRARY_DIRS})

endif( PostgreSQL_FOUND ) ... Remember to include
${PostgreSQL_LIBRARIES} in the target_link_libraries() statement.

In Windows, we make the assumption that, if the PostgreSQL files are
installed, the default directory will be C:\Program Files\PostgreSQL.

FindProducer

Though Producer isn't directly part of OpenSceneGraph, its primary
user is OSG so I consider this part of the Findosg* suite used to find
OpenSceneGraph components. You'll notice that I accept OSGDIR as an
environment path.

Each component is separate and you must opt in to each module. You
must also opt into OpenGL (and OpenThreads?) as these modules won't do
it for you. This is to allow you control over your own system piece
by piece in case you need to opt out of certain components or change
the Find behavior for a particular module (perhaps because the default
FindOpenGL.cmake module doesn't work with your system as an example).
If you want to use a more convenient module that includes everything,
use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake
modules.

Locate Producer This module defines PRODUCER_LIBRARY PRODUCER_FOUND,
if false, do not try to link to Producer PRODUCER_INCLUDE_DIR, where
to find the headers

$PRODUCER_DIR is an environment variable that would correspond to the
./configure --prefix=$PRODUCER_DIR used in building osg.

Created by Eric Wing.

FindProtobuf

Locate and configure the Google Protocol Buffers library. Defines the
following variables:

PROTOBUF_FOUND - Found the Google Protocol Buffers library
PROTOBUF_INCLUDE_DIRS - Include directories for Google Protocol Buffers
PROTOBUF_LIBRARIES - The protobuf library

The following cache variables are also defined:

PROTOBUF_LIBRARY - The protobuf library
PROTOBUF_PROTOC_LIBRARY - The protoc library
PROTOBUF_INCLUDE_DIR - The include directory for protocol buffers
PROTOBUF_PROTOC_EXECUTABLE - The protoc compiler

====================================================================
Example:

find_package(Protobuf REQUIRED)
include_directories(${PROTOBUF_INCLUDE_DIRS})

include_directories(${CMAKE_CURRENT_BINARY_DIR})
PROTOBUF_GENERATE_CPP(PROTO_SRCS PROTO_HDRS foo.proto)
add_executable(bar bar.cc ${PROTO_SRCS} ${PROTO_HDRS})
target_link_libraries(bar ${PROTOBUF_LIBRARY})

NOTE: You may need to link against pthreads, depending on the
platform.

====================================================================

PROTOBUF_GENERATE_CPP (public function)

SRCS = Variable to define with autogenerated
source files
HDRS = Variable to define with autogenerated
header files
ARGN = proto files

====================================================================

FindPythonInterp
Find python interpreter

This module finds if Python interpreter is installed and determines
where the executables are. This code sets the following variables:

PYTHONINTERP_FOUND - Was the Python executable found
PYTHON_EXECUTABLE - path to the Python interpreter
Python_ADDITIONAL_VERSIONS - list of additional Python versions to search for

FindPythonLibs
Find python libraries

This module finds if Python is installed and determines where the
include files and libraries are. It also determines what the name of
the library is. This code sets the following variables:

PYTHONLIBS_FOUND - have the Python libs been found
PYTHON_LIBRARIES - path to the python library
PYTHON_INCLUDE_PATH - path to where Python.h is found (deprecated)
PYTHON_INCLUDE_DIRS - path to where Python.h is found
PYTHON_DEBUG_LIBRARIES - path to the debug library
Python_ADDITIONAL_VERSIONS - list of additional Python versions to search for

FindQt
Searches for all installed versions of QT.

This should only be used if your project can work with multiple
versions of QT. If not, you should just directly use FindQt4 or
FindQt3. If multiple versions of QT are found on the machine, then
The user must set the option DESIRED_QT_VERSION to the version they
want to use. If only one version of qt is found on the machine, then
the DESIRED_QT_VERSION is set to that version and the matching FindQt3
or FindQt4 module is included. Once the user sets DESIRED_QT_VERSION,
then the FindQt3 or FindQt4 module is included.

QT_REQUIRED if this is set to TRUE then if CMake can
not find QT4 or QT3 an error is raised
and a message is sent to the user.

DESIRED_QT_VERSION OPTION is created
QT4_INSTALLED is set to TRUE if qt4 is found.
QT3_INSTALLED is set to TRUE if qt3 is found.

FindQt3
Locate Qt include paths and libraries

This module defines:

QT_INCLUDE_DIR - where to find qt.h, etc.
QT_LIBRARIES - the libraries to link against to use Qt.
QT_DEFINITIONS - definitions to use when
compiling code that uses Qt.
QT_FOUND - If false, don't try to use Qt.

If you need the multithreaded version of Qt, set QT_MT_REQUIRED to
TRUE

Also defined, but not for general use are:

QT_MOC_EXECUTABLE, where to find the moc tool.
QT_UIC_EXECUTABLE, where to find the uic tool.
QT_QT_LIBRARY, where to find the Qt library.
QT_QTMAIN_LIBRARY, where to find the qtmain
library. This is only required by Qt3 on Windows.

FindQt4
Find QT 4

This module can be used to find Qt4. The most important issue is that
the Qt4 qmake is available via the system path. This qmake is then
used to detect basically everything else. This module defines a
number of key variables and macros. The variable QT_USE_FILE is set
which is the path to a CMake file that can be included to compile Qt 4
applications and libraries. It sets up the compilation environment
for include directories, preprocessor defines and populates a
QT_LIBRARIES variable.

Typical usage could be something like:

find_package(Qt4 4.4.3 COMPONENTS QtCore QtGui QtXml REQUIRED )
include(${QT_USE_FILE})
add_executable(myexe main.cpp)
target_link_libraries(myexe ${QT_LIBRARIES})

The minimum required version can be specified using the standard
find_package()-syntax (see example above). For compatibility with
older versions of FindQt4.cmake it is also possible to set the
variable QT_MIN_VERSION to the minimum required version of Qt4 before
the find_package(Qt4) command. If both are used, the version used in
the find_package() command overrides the one from QT_MIN_VERSION.

When using the components argument, QT_USE_QT* variables are
automatically set for the QT_USE_FILE to pick up. If one wishes to
manually set them, the available ones to set include:

QT_DONT_USE_QTCORE
QT_DONT_USE_QTGUI
QT_USE_QT3SUPPORT
QT_USE_QTASSISTANT
QT_USE_QAXCONTAINER
QT_USE_QAXSERVER
QT_USE_QTDESIGNER
QT_USE_QTMOTIF
QT_USE_QTMAIN
QT_USE_QTMULTIMEDIA
QT_USE_QTNETWORK
QT_USE_QTNSPLUGIN
QT_USE_QTOPENGL
QT_USE_QTSQL
QT_USE_QTXML
QT_USE_QTSVG
QT_USE_QTTEST
QT_USE_QTUITOOLS
QT_USE_QTDBUS
QT_USE_QTSCRIPT
QT_USE_QTASSISTANTCLIENT
QT_USE_QTHELP
QT_USE_QTWEBKIT
QT_USE_QTXMLPATTERNS
QT_USE_PHONON
QT_USE_QTSCRIPTTOOLS
QT_USE_QTDECLARATIVE

QT_USE_IMPORTED_TARGETS
If this variable is set to TRUE, FindQt4.cmake will create imported
library targets for the various Qt libraries and set the
library variables like QT_QTCORE_LIBRARY to point at these imported
targets instead of the library file on disk. This provides much better
handling of the release and debug versions of the Qt libraries and is
also always backwards compatible, except for the case that dependencies
of libraries are exported, these will then also list the names of the
imported targets as dependency and not the file location on disk. This
is much more flexible, but requires that FindQt4.cmake is executed before
such an exported dependency file is processed.

There are also some files that need processing by some Qt tools such
as moc and uic. Listed below are macros that may be used to process
those files.

macro QT4_WRAP_CPP(outfiles inputfile ... OPTIONS ...)
create moc code from a list of files containing Qt class with
the Q_OBJECT declaration. Per-direcotry preprocessor definitions
are also added. Options may be given to moc, such as those found
when executing "moc -help".

macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
create code from a list of Qt designer ui files.
Options may be given to uic, such as those found
when executing "uic -help"

macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
create code from a list of Qt resource files.
Options may be given to rcc, such as those found
when executing "rcc -help"

macro QT4_GENERATE_MOC(inputfile outputfile )
creates a rule to run moc on infile and create outfile.
Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
because you need a custom filename for the moc file or something similar.

macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... )
This macro is still experimental.
It can be used to have moc automatically handled.
So if you have the files foo.h and foo.cpp, and in foo.h a
a class uses the Q_OBJECT macro, moc has to run on it. If you don't
want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
#include "foo.moc"
in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the
scan all listed files at cmake-time for such included moc files and if it finds
them cause a rule to be generated to run moc at build time on the
accompanying header file foo.h.
If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.

macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
create a the interface header and implementation files with the
given basename from the given interface xml file and add it to
the list of sources

macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
create the interface header and implementation files
for all listed interface xml files
the name will be automatically determined from the name of the xml file

macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname [basename] [classname])
create a dbus adaptor (header and implementation file) from the xml file
describing the interface, and add it to the list of sources. The adaptor
forwards the calls to a parent class, defined in parentheader and named
parentclassname. The name of the generated files will be
<basename>adaptor.{cpp,h} where basename defaults to the basename of the xml file.
If <classname> is provided, then it will be used as the classname of the
adaptor itself.

macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...)
generate the xml interface file from the given header.
If the optional argument interfacename is omitted, the name of the
interface file is constructed from the basename of the header with
the suffix .xml appended.
Options may be given to qdbuscpp2xml, such as those found when executing "qdbuscpp2xml --help"

macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ...
ts_files ... OPTIONS ...)
out: qm_files
in: directories sources ts_files
options: flags to pass to lupdate, such as -extensions to specify
extensions for a directory scan.
generates commands to create .ts (vie lupdate) and .qm
(via lrelease) - files from directories and/or sources. The ts files are
created and/or updated in the source tree (unless given with full paths).
The qm files are generated in the build tree.
Updating the translations can be done by adding the qm_files
to the source list of your library/executable, so they are
always updated, or by adding a custom target to control when
they get updated/generated.

macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
out: qm_files
in: ts_files
generates commands to create .qm from .ts - files. The generated
filenames can be found in qm_files. The ts_files
must exists and are not updated in any way.

These are around for backwards compatibility they will be set

QT_WRAP_CPP Set true if QT_MOC_EXECUTABLE is found
QT_WRAP_UI Set true if QT_UIC_EXECUTABLE is found

These variables do _NOT_ have any effect anymore (compared to
FindQt.cmake)

QT_MT_REQUIRED Qt4 is now always multithreaded

These variables are set to "" Because Qt structure changed (They make
no sense in Qt4)

QT_QT_LIBRARY Qt-Library is now split

FindQuickTime

Locate QuickTime This module defines QUICKTIME_LIBRARY
QUICKTIME_FOUND, if false, do not try to link to gdal
QUICKTIME_INCLUDE_DIR, where to find the headers

$QUICKTIME_DIR is an environment variable that would correspond to the
./configure --prefix=$QUICKTIME_DIR

Created by Eric Wing.

FindRTI
Try to find M&S HLA RTI libraries

This module finds if any HLA RTI is installed and locates the standard
RTI include files and libraries.

RTI is a simulation infrastructure standardized by IEEE and SISO. It
has a well defined C++ API that assures that simulation applications
are independent on a particular RTI implementation.

http://en.wikipedia.org/wiki/Run-Time_Infrastructure_(simulation)

This code sets the following variables:

RTI_INCLUDE_DIR = the directory where RTI includes file are found
RTI_LIBRARIES = The libraries to link against to use RTI
RTI_DEFINITIONS = -DRTI_USES_STD_FSTREAM
RTI_FOUND = Set to FALSE if any HLA RTI was not found

Report problems to <certi-devel@nongnu.org>

FindRuby
Find Ruby

This module finds if Ruby is installed and determines where the
include files and libraries are. Ruby 1.8 and 1.9 are supported.

The minimum required version of Ruby can be specified using the
standard syntax, e.g. FIND_PACKAGE(Ruby 1.8)

It also determines what the name of the library is. This code sets
the following variables:

RUBY_EXECUTABLE = full path to the ruby binary
RUBY_INCLUDE_DIRS = include dirs to be used when using the ruby library
RUBY_LIBRARY = full path to the ruby library
RUBY_VERSION = the version of ruby which was found, e.g. "1.8.7"
RUBY_FOUND = set to true if ruby ws found successfully

RUBY_INCLUDE_PATH = same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don't use it

FindSDL

Locate SDL library This module defines SDL_LIBRARY, the name of the
library to link against SDL_FOUND, if false, do not try to link to SDL
SDL_INCLUDE_DIR, where to find SDL.h

This module responds to the the flag: SDL_BUILDING_LIBRARY If this is
defined, then no SDL_main will be linked in because only applications
need main(). Otherwise, it is assumed you are building an application
and this module will attempt to locate and set the the proper link
flags as part of the returned SDL_LIBRARY variable.

Don't forget to include SDLmain.h and SDLmain.m your project for the
OS X framework based version. (Other versions link to -lSDLmain which
this module will try to find on your behalf.) Also for OS X, this
module will automatically add the -framework Cocoa on your behalf.

Additional Note: If you see an empty SDL_LIBRARY_TEMP in your
configuration and no SDL_LIBRARY, it means CMake did not find your SDL
library (SDL.dll, libsdl.so, SDL.framework, etc). Set
SDL_LIBRARY_TEMP to point to your SDL library, and configure again.
Similarly, if you see an empty SDLMAIN_LIBRARY, you should set this
value as appropriate. These values are used to generate the final
SDL_LIBRARY variable, but when these values are unset, SDL_LIBRARY
does not get created.

$SDLDIR is an environment variable that would correspond to the
./configure --prefix=$SDLDIR used in building SDL. l.e.galup 9-20-02

Modified by Eric Wing. Added code to assist with automated building
by using environmental variables and providing a more
controlled/consistent search behavior. Added new modifications to
recognize OS X frameworks and additional Unix paths (FreeBSD, etc).
Also corrected the header search path to follow "proper" SDL
guidelines. Added a search for SDLmain which is needed by some
platforms. Added a search for threads which is needed by some
platforms. Added needed compile switches for MinGW.

On OSX, this will prefer the Framework version (if found) over others.
People will have to manually change the cache values of SDL_LIBRARY to
override this selection or set the CMake environment
CMAKE_INCLUDE_PATH to modify the search paths.

Note that the header path has changed from SDL/SDL.h to just SDL.h
This needed to change because "proper" SDL convention is #include
"SDL.h", not <SDL/SDL.h>. This is done for portability reasons
because not all systems place things in SDL/ (see FreeBSD).

FindSDL_image

Locate SDL_image library This module defines SDLIMAGE_LIBRARY, the
name of the library to link against SDLIMAGE_FOUND, if false, do not
try to link to SDL SDLIMAGE_INCLUDE_DIR, where to find SDL/SDL.h

$SDLDIR is an environment variable that would correspond to the
./configure --prefix=$SDLDIR used in building SDL.

Created by Eric Wing. This was influenced by the FindSDL.cmake
module, but with modifications to recognize OS X frameworks and
additional Unix paths (FreeBSD, etc).

FindSDL_mixer

Locate SDL_mixer library This module defines SDLMIXER_LIBRARY, the
name of the library to link against SDLMIXER_FOUND, if false, do not
try to link to SDL SDLMIXER_INCLUDE_DIR, where to find SDL/SDL.h

$SDLDIR is an environment variable that would correspond to the
./configure --prefix=$SDLDIR used in building SDL.

Created by Eric Wing. This was influenced by the FindSDL.cmake
module, but with modifications to recognize OS X frameworks and
additional Unix paths (FreeBSD, etc).

FindSDL_net

Locate SDL_net library This module defines SDLNET_LIBRARY, the name of
the library to link against SDLNET_FOUND, if false, do not try to link
against SDLNET_INCLUDE_DIR, where to find the headers

$SDLDIR is an environment variable that would correspond to the
./configure --prefix=$SDLDIR used in building SDL.

Created by Eric Wing. This was influenced by the FindSDL.cmake
module, but with modifications to recognize OS X frameworks and
additional Unix paths (FreeBSD, etc).

FindSDL_sound

Locates the SDL_sound library

FindSDL_ttf

Locate SDL_ttf library This module defines SDLTTF_LIBRARY, the name of
the library to link against SDLTTF_FOUND, if false, do not try to link
to SDL SDLTTF_INCLUDE_DIR, where to find SDL/SDL.h

$SDLDIR is an environment variable that would correspond to the
./configure --prefix=$SDLDIR used in building SDL.

Created by Eric Wing. This was influenced by the FindSDL.cmake
module, but with modifications to recognize OS X frameworks and
additional Unix paths (FreeBSD, etc).

FindSWIG
Find SWIG

This module finds an installed SWIG. It sets the following variables:

SWIG_FOUND - set to true if SWIG is found
SWIG_DIR - the directory where swig is installed
SWIG_EXECUTABLE - the path to the swig executable
SWIG_VERSION - the version number of the swig executable

The minimum required version of SWIG can be specified using the
standard syntax, e.g. FIND_PACKAGE(SWIG 1.1)

All information is collected from the SWIG_EXECUTABLE so the version
to be found can be changed from the command line by means of setting
SWIG_EXECUTABLE

FindSelfPackers
Find upx

This module looks for some executable packers (i.e. softwares that
compress executables or shared libs into on-the-fly self-extracting
executables or shared libs. Examples:

UPX: http://wildsau.idv.uni-linz.ac.at/mfx/upx.html

FindSquish
-- Typical Use

This module can be used to find Squish (currently support is aimed at
version 3).

SQUISH_FOUND If false, don't try to use Squish

SQUISH_INSTALL_DIR The Squish installation directory (containing bin, lib, etc)
SQUISH_SERVER_EXECUTABLE The squishserver executable
SQUISH_CLIENT_EXECUTABLE The squishrunner executable

SQUISH_INSTALL_DIR_FOUND Was the install directory found?
SQUISH_SERVER_EXECUTABLE_FOUND Was the server executable found?
SQUISH_CLIENT_EXECUTABLE_FOUND Was the client executable found?

macro SQUISH_ADD_TEST(testName applicationUnderTest testSuite
testCase)

ENABLE_TESTING()
FIND_PACKAGE(Squish)
IF (SQUISH_FOUND)
SQUISH_ADD_TEST(myTestName myApplication testSuiteName testCaseName)
ENDIF (SQUISH_FOUND)

FindSubversion
Extract information from a subversion working copy

The module defines the following variables:

Subversion_SVN_EXECUTABLE - path to svn command line client
Subversion_VERSION_SVN - version of svn command line client
Subversion_FOUND - true if the command line client was found
SUBVERSION_FOUND - same as Subversion_FOUND, set for compatiblity reasons

The minimum required version of Subversion can be specified using the
standard syntax, e.g. FIND_PACKAGE(Subversion 1.4)

If the command line client executable is found two macros are defined:

Subversion_WC_INFO(<dir> <var-prefix>)
Subversion_WC_LOG(<dir> <var-prefix>)

Subversion_WC_INFO extracts information of a subversion working copy
at a given location. This macro defines the following variables:

<var-prefix>_WC_URL - url of the repository (at <dir>)
<var-prefix>_WC_ROOT - root url of the repository
<var-prefix>_WC_REVISION - current revision
<var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
<var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
<var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
<var-prefix>_WC_INFO - output of command `svn info <dir>'

Subversion_WC_LOG retrieves the log message of the base revision of a
subversion working copy at a given location. This macro defines the
variable:

<var-prefix>_LAST_CHANGED_LOG - last log of base revision

Example usage:

FIND_PACKAGE(Subversion)
IF(SUBVERSION_FOUND)
Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
MESSAGE("Current revision is ${Project_WC_REVISION}")
Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
MESSAGE("Last changed log is ${Project_LAST_CHANGED_LOG}")
ENDIF(SUBVERSION_FOUND)

FindTCL
TK_INTERNAL_PATH was removed.

This module finds if Tcl is installed and determines where the include
files and libraries are. It also determines what the name of the
library is. This code sets the following variables:

TCL_FOUND = Tcl was found
TK_FOUND = Tk was found
TCLTK_FOUND = Tcl and Tk were found
TCL_LIBRARY = path to Tcl library (tcl tcl80)
TCL_INCLUDE_PATH = path to where tcl.h can be found
TCL_TCLSH = path to tclsh binary (tcl tcl80)
TK_LIBRARY = path to Tk library (tk tk80 etc)
TK_INCLUDE_PATH = path to where tk.h can be found
TK_WISH = full path to the wish executable

In an effort to remove some clutter and clear up some issues for
people who are not necessarily Tcl/Tk gurus/developpers, some
variables were moved or removed. Changes compared to CMake 2.4 are:

=> they were only useful for people writing Tcl/Tk extensions.
=> these libs are not packaged by default with Tcl/Tk distributions.
Even when Tcl/Tk is built from source, several flavors of debug libs
are created and there is no real reason to pick a single one
specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx).
Let's leave that choice to the user by allowing him to assign
TCL_LIBRARY to any Tcl library, debug or not.
=> this ended up being only a Win32 variable, and there is a lot of
confusion regarding the location of this file in an installed Tcl/Tk
tree anyway (see 8.5 for example). If you need the internal path at
this point it is safer you ask directly where the *source* tree is
and dig from there.

FindTIFF
Find TIFF library

Find the native TIFF includes and library This module defines

TIFF_INCLUDE_DIR, where to find tiff.h, etc.
TIFF_LIBRARIES, libraries to link against to use TIFF.
TIFF_FOUND, If false, do not try to use TIFF.

also defined, but not for general use are

TIFF_LIBRARY, where to find the TIFF library.

FindTclStub
TCL_STUB_LIBRARY_DEBUG and TK_STUB_LIBRARY_DEBUG were removed.

This module finds Tcl stub libraries. It first finds Tcl include
files and libraries by calling FindTCL.cmake. How to Use the Tcl
Stubs Library:

http://tcl.activestate.com/doc/howto/stubs.html

Using Stub Libraries:

http://safari.oreilly.com/0130385603/ch48lev1sec3

This code sets the following variables:

TCL_STUB_LIBRARY = path to Tcl stub library
TK_STUB_LIBRARY = path to Tk stub library
TTK_STUB_LIBRARY = path to ttk stub library

In an effort to remove some clutter and clear up some issues for
people who are not necessarily Tcl/Tk gurus/developpers, some
variables were moved or removed. Changes compared to CMake 2.4 are:

=> these libs are not packaged by default with Tcl/Tk distributions.
Even when Tcl/Tk is built from source, several flavors of debug libs
are created and there is no real reason to pick a single one
specifically (say, amongst tclstub84g, tclstub84gs, or tclstub84sgx).
Let's leave that choice to the user by allowing him to assign
TCL_STUB_LIBRARY to any Tcl library, debug or not.

FindTclsh
Find tclsh

This module finds if TCL is installed and determines where the include
files and libraries are. It also determines what the name of the
library is. This code sets the following variables:

TCLSH_FOUND = TRUE if tclsh has been found
TCL_TCLSH = the path to the tclsh executable

In cygwin, look for the cygwin version first. Don't look for it later
to avoid finding the cygwin version on a Win32 build.

FindThreads
This module determines the thread library of the system.

The following variables are set

CMAKE_THREAD_LIBS_INIT - the thread library
CMAKE_USE_SPROC_INIT - are we using sproc?
CMAKE_USE_WIN32_THREADS_INIT - using WIN32 threads?
CMAKE_USE_PTHREADS_INIT - are we using pthreads
CMAKE_HP_PTHREADS_INIT - are we using hp pthreads

For systems with multiple thread libraries, caller can set

CMAKE_THREAD_PREFER_PTHREAD

FindUnixCommands
Find unix commands from cygwin

This module looks for some usual Unix commands.

FindVTK
Find a VTK installation or build tree.

The following variables are set if VTK is found. If VTK is not found,
VTK_FOUND is set to false.

VTK_FOUND - Set to true when VTK is found.
VTK_USE_FILE - CMake file to use VTK.
VTK_MAJOR_VERSION - The VTK major version number.
VTK_MINOR_VERSION - The VTK minor version number
(odd non-release).
VTK_BUILD_VERSION - The VTK patch level
(meaningless for odd minor).
VTK_INCLUDE_DIRS - Include directories for VTK
VTK_LIBRARY_DIRS - Link directories for VTK libraries
VTK_KITS - List of VTK kits, in CAPS
(COMMON,IO,) etc.
VTK_LANGUAGES - List of wrapped languages, in CAPS
(TCL, PYHTON,) etc.

The following cache entries must be set by the user to locate VTK:

VTK_DIR - The directory containing VTKConfig.cmake.
This is either the root of the build tree,
or the lib/vtk directory. This is the
only cache entry.

The following variables are set for backward compatibility and should
not be used in new code:

USE_VTK_FILE - The full path to the UseVTK.cmake file.
This is provided for backward
compatibility. Use VTK_USE_FILE
instead.

FindWget
Find wget

This module looks for wget. This module defines the following values:

WGET_EXECUTABLE: the full path to the wget tool.
WGET_FOUND: True if wget has been found.

FindWish
Find wish installation

This module finds if TCL is installed and determines where the include
files and libraries are. It also determines what the name of the
library is. This code sets the following variables:

TK_WISH = the path to the wish executable

if UNIX is defined, then it will look for the cygwin version first

FindX11
Find X11 installation

Try to find X11 on UNIX systems. The following values are defined

X11_FOUND - True if X11 is available
X11_INCLUDE_DIR - include directories to use X11

FindXMLRPC
Find xmlrpc

Find the native XMLRPC headers and libraries.

XMLRPC_INCLUDE_DIRS - where to find xmlrpc.h, etc.
XMLRPC_LIBRARIES - List of libraries when using xmlrpc.
XMLRPC_FOUND - True if xmlrpc found.

XMLRPC modules may be specified as components for this find module.
Modules may be listed by running "xmlrpc-c-config". Modules include:

c++ C++ wrapper code
libwww-client libwww-based client
cgi-server CGI-based server
abyss-server ABYSS-based server

Typical usage:

FIND_PACKAGE(XMLRPC REQUIRED libwww-client)

FindZLIB
Find zlib

Find the native ZLIB includes and library. Once done this will define

ZLIB_INCLUDE_DIRS - where to find zlib.h, etc.
ZLIB_LIBRARIES - List of libraries when using zlib.
ZLIB_FOUND - True if zlib found.

ZLIB_VERSION_STRING - The version of zlib found (x.y.z)
ZLIB_VERSION_MAJOR - The major version of zlib
ZLIB_VERSION_MINOR - The minor version of zlib
ZLIB_VERSION_PATCH - The patch version of zlib
ZLIB_VERSION_TWEAK - The tweak version of zlib

The following variable are provided for backward compatibility

ZLIB_MAJOR_VERSION - The major version of zlib
ZLIB_MINOR_VERSION - The minor version of zlib
ZLIB_PATCH_VERSION - The patch version of zlib

Findosg

NOTE: It is highly recommended that you use the new
FindOpenSceneGraph.cmake introduced in CMake 2.6.3 and not use this
Find module directly.

This is part of the Findosg* suite used to find OpenSceneGraph
components. Each component is separate and you must opt in to each
module. You must also opt into OpenGL and OpenThreads (and Producer
if needed) as these modules won't do it for you. This is to allow you
control over your own system piece by piece in case you need to opt
out of certain components or change the Find behavior for a particular
module (perhaps because the default FindOpenGL.cmake module doesn't
work with your system as an example). If you want to use a more
convenient module that includes everything, use the
FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

Locate osg This module defines

OSG_FOUND - Was the Osg found? OSG_INCLUDE_DIR - Where to find the
headers OSG_LIBRARIES - The libraries to link against for the OSG (use
this)

OSG_LIBRARY - The OSG library OSG_LIBRARY_DEBUG - The OSG debug
library
