Usage: $(color 4 ${0}) [--$(color 5 recompile)] [--$(color 1 debug)] — Build $PROJECT
          --$(color 5 recompile)   — Delete $(color 6 \$COMPILEDIR) (release_build or debug_build with --$(color 1 debug)) before compiling $PROJECT again
          --$(color 1 debug)       — Make a $(color 1 debug) build

All extra parameters are passed to cmake.
Environment variables:
          CROSS         — Set to "mingw64" to cross-compile for Windows
