I think MPI should be disabled by default instead. If MPI is useful only
when PETSc and/or SCOTCH is enabled, it will be only one case where the
user has to turn on MPI manually with the enableMpi option and that is
when SCOTCH is enabled and PETSc is disabled. MPI will be enabled
automatically if PETSc is enabled and PETSc is built with MPI.
