Summary0010998: MPI_COMPILER defaults to mpicxx, doesn't work for Fortran only
DescriptionFindMPI module looks for the C++ mpi compiler (mpicxx, mpiCC) wrapper to set the MPI_COMPILER. But for Fortran only projects, this doesn't work since one of C++ specific MPI libraries are added at the linker stage. (same goes for C only projects, but I haven't checked the actual behavior).

This module can be made a bit smarter to detect whether C++ is enabled, and if not, try to locate fortran (mpif90, mpif77), or C (mpicc) compiler wrappers to resolve MPI_LIBRARIES.

Note that, this is not really a fatal problem since MPI_COMPILER can be manually set in CMakeLists.txt (bad), or during the build (showstopper).

This module has been vastly re-factored in CMake 2.8.4, properly distinguishing between C/C++/Fortran compilers. When 2.8.4-RC1 is released please try it out and let us know if you still have any issues by reopening this bug or creating a new one.
