Just specify where each individual MPI distribution's stuff is on the
command line when you compile with mpicc *.c -I$MPICH_HOME/include or
mpicc *.c -I$OPENMPI_HOME/include where the "HOME" directories were
specified with --prefix= when you installed. Hope this helps. This
works for me. Hope this helps. Cheers!
