What does "mpic++ -showme hello.cxx" say? (Or is it more like
"mpic++.exe /showme hello.cxx" on windows?)

This is a very strange path.

Are the libraries actually there?

I have:
MPI_CXX_LIBRARIES:STRING=/usr/lib64/openmpi/lib/libmpi_cxx.so;/usr/lib64/openmpi/lib/libmpi.so;/usr/lib64/libdl.so

So if you have to set MPI_LIBRARY manually just add everything that
mpic++ does separated by ';'.
