<p>Add an <code class="docutils literal notranslate"><span class="pre">uninstall</span></code> target.</p>
<p>By including this module, an <code class="docutils literal notranslate"><span class="pre">uninstall</span></code> target will be added to your CMake
project. This will remove all files installed (or updated) by a previous
invocation of the <code class="docutils literal notranslate"><span class="pre">install</span></code> target. It will not remove files created or
modified by an <code class="docutils literal notranslate"><span class="pre">install(SCRIPT)</span></code> or <code class="docutils literal notranslate"><span class="pre">install(CODE)</span></code> command; you should
create a custom uninstallation target for these and use <code class="docutils literal notranslate"><span class="pre">add_dependency</span></code> to
make the <code class="docutils literal notranslate"><span class="pre">uninstall</span></code> target depend on it:</p>
<div class="highlight-cmake notranslate"><div class="highlight"><pre><span></span><span class="nb">include</span><span class="p">(</span><span class="s">ECMUninstallTarget</span><span class="p">)</span>
<span class="nb">install</span><span class="p">(</span><span class="s">SCRIPT</span> <span class="s">install-foo.cmake</span><span class="p">)</span>
<span class="nb">add_custom_target</span><span class="p">(</span><span class="s">uninstall_foo</span> <span class="s">COMMAND</span> <span class="o">${</span><span class="nv">CMAKE_COMMAND</span><span class="o">}</span> <span class="s">-P</span> <span class="s">uninstall-foo.cmake</span><span class="p">)</span>
<span class="nb">add_dependency</span><span class="p">(</span><span class="s">uninstall</span> <span class="s">uninstall_foo</span><span class="p">)</span>
</pre></div>
</div>
<p>The target will fail if the <code class="docutils literal notranslate"><span class="pre">install</span></code> target has not yet been run (so it is
not possible to run CMake on the project and then immediately run the
<code class="docutils literal notranslate"><span class="pre">uninstall</span></code> target).</p>
<div class="admonition warning">
<p class="first admonition-title">Warning</p>
<p class="last">CMake deliberately does not provide an <code class="docutils literal notranslate"><span class="pre">uninstall</span></code> target by default on
the basis that such a target has the potential to remove important files
from a user’s computer. Use with caution.</p>
