define LIBP_HELP_MSG

LIBP Benchmarks makefile targets:

	 make all (default)
	 make BP/BK/BS
	 make clean
	 make clean-libs
	 make realclean
	 make info
	 make help

Usage:

make all
	 Builds all benchmark executables.
make BP/BK
	 Builds Bakeoff Problem or Kernel executables,
make clean
	 Cleans all executables and object files.
make clean-BP/BK
	 Cleans BP or BK executables and object files.
make clean-libs
	 In addition to "make clean", also clean the core, mesh, and ogs libraries.
make clean-kernels
   In addition to "make clean-libs", also cleans the cached OCCA kernels.
make realclean
	 In addition to "make clean-libs", also clean 3rd party libraries.
make info
	 List directories and compiler flags in use.
make help
	 Display this help message.

Can use "make verbose=true" for verbose output.
