# make-cmake-make
# Uses Cmake to make makefiles. Execute the script in the source directory to
# create a build directory and Cmake build artefacts in it including a Makefile.
# The first argument is one of the two toolchains: Gnu (default) or Clang.
# The second argument is one of the following build types: 
#	Debug, Release (default), RelWithDebInfo or MinSizeRel

# Usage examples:
#	make-cmake-make Gnu Release
#	make-cmake-make Gnu Debug
#	make-cmake-make Clang Release
#	make-cmake-make Clang Debug
