OPT = -O2
## As the Armadillo library uses recursive templates, compilation times depend on the level of optimisation:
##
## -O0: quick compilation, but the resulting program will be slow
## -O1: good trade-off between compilation time and execution speed
## -O2: produces programs which have almost all possible speedups, but compilation takes longer
## -O3: enables auto vectorisation when using gcc
