define HIPBONE_HELP_MSG

hipBone makefile targets:

   make hipBone (default)
   make clean
   make clean-libs
   make clean-kernels
   make realclean
   make install
   make info
   make help

Usage:

make hipBone
   Build hipBone executable.
make clean
   Clean the hipBone executable and object files.
make clean-libs
   In addition to "make clean", also clean the mesh, ogs, and core libraries.
make clean-kernels
   In addition to "make clean-libs", also cleans the cached OCCA kernels.
make realclean
   In addition to "make clean-kernels", also clean 3rd party libraries.
make install PREFIX=<path>
   Install hipBone and okl files to PREFIX location (default hipBone/install).
make info
   List directories and compiler flags in use.
make help
   Display this help message.

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