On my machine, "mpicc -showme:compile" outputs "-pthread" only.
I guess CMake is modeling MPI recognizing after MPICH, and that "-I"
flags appears in "mpicc -showme:compile" output there; tried to check
that, but latest MPICH (1.0.7) won't even compile on my machine... In
any case, I reported the issue to the CMake bug tracker too.
