Fixing a mistake in the main CMakeLists.txt where 'CMAKE_REQUIRED_INCLUDE' was improperly set instead of 'CMAKE_REQUIRED_INCLUDES' for checking for a proper MPI configuration. Also, the test for 'MPI_Comm_f2c' was also modified since the old approach would not work for macro definitions (as in MPICH2).
