So, the real issue here is that mpicc does not support all of the flags 
that the compiler it is wrapping supports....  If you use gcc, it works 
right?

CMake did recognize that it was GNU:
  -- The C compiler identification is GNU
     -- The CXX compiler identification is GNU

My previous post was incorrect, it is not matching the name of the 
compiler.
