define DAWGS_HELP_MSG

DAWGS makefile targets:

   make dawgsMain (default)
   make clean
   make clean-libs
   make clean-kernels
   make realclean
   make info
   make help
   make test

Usage:

make dawgsMain
   Build dawgsMain executable.
make clean
   Clean the dawgsMain executable, library, and object files.
make clean-libs
   In addition to "make clean", also clean needed 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 info
   List directories and compiler flags in use.
make help
   Display this help message.
make test
   Run tests.

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