This project is built using CMake.
If you are familiar with CMake, you may invoke it directly.
If you are not familiar with CMake, this script can help select the best
options for CMake and invoke it for you.

Options:
	--debug          build an executable with debugging information.
	--release        build an optimized executable for release.
	--prefix <path>  specify the installation prefix.
