[CMake] How can I change the compiler?

["Sören Freudiger"]

That's right. But on bad configured cluster systems you have a lot of different mpi-compilers. I don't know what changes had have been done to the findMPI modul. But the last version I tried wasn't satisfying.

And all you need to now are the compilers and the mpi library...

It is probably worth considering 
	find_package( MPI )
This will not only set the MPI compilers but also defines the mpi executable, etc.
