If they are not found that only means they were not in one of the standard 
places that cmake checks. I doubt it checks your home directory. So just set 
those values manually with ccmake or cmake -i.

I think ParaView will work with any MPI library. The important question is 
which version of MPI works best on your hardware? That is, which produces the 
fastest results without errors or failures.

Use only one, whichever works best.
