[Paraview-developers] [EXTERNAL] Re: Bad superbuild

[Chuck Atkins]

Yes, that's generally the most reliable way to get the correct and complete
MPI support.  I suspect the FindMPI module was getting half-baked
information from the wrappers and augmenting with the specified
MPI_INCLUDE_PATH.  If you don't want it in the environment then I would try
explicitly setting the compiler wrappers and nothing else with:

-DMPI_C_COMPILER:FILEPATH=/opt/openmpi-1.8-gnu//bin/mpicc
-DMPI_CXX_COMPILER:FILEPATH=/opt/openmpi-1.8-gnu//bin/mpicxx

and drop any other MPI_FOO vars, leaving the FindMPI module interrogate the
wrappers to populate the rest.
