define LIBP_HELP_MSG

LibParanumal makefile targets:

	 make solvers (default)
	 make {solver}
	 make clean
	 make clean-kernels
	 make realclean
	 make info
	 make help
	 make test

Usage:

make solvers
	 Builds each solver executable.
make {solver}
	 Builds a solver executable,
	 solver can be acoustics/advection/bns/cns/elliptic/fokkerPlanck/gradient/ins/maxwell.
make clean
	 Cleans all solver executables, libraries, and object files.
make clean-{solver}
	 Cleans a solve executable, library, and object files.
make clean-kernels
	 In addition to "make clean", also cleans the cached OCCA kernels.
make realclean
	 In addition to "make clean", also clean 3rd party libraries.
make info
	 List directories and compiler flags in use.
make help
	 Display this help message.
make test
	 Run the included solver examples.

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