From the CMake 2.8.5 FindMPI:

# The compilers are detected in this order:
#
# 1. Try to find the most generic availble MPI compiler, as this is usually set up by
# cluster admins. e.g., if plain old mpicc is available, we'll use it and assume it's
# the right compiler.
#
# 2. If a generic mpicc is NOT found, then we attempt to find one that matches
# CMAKE__COMPILER_ID. e.g. if you are using XL compilers, we'll try to find mpixlc
# and company, but not mpiicc. This hopefully prevents toolchain mismatches.
#
# If you want to force a particular MPI compiler other than what we autodetect (e.g. if you
# want to compile regular stuff with GNU and parallel stuff with Intel), you can always set
# your favorite MPI__COMPILER explicitly and this stuff will be ignored.
#

As always, I prefer to stick as close to standard behavior as possible, this avoids surprises for new users. But if you see a way to make things easier without breaking the other builds, feel free to change it. I think in the case of Qt Creator on the mac, the problem may be that the mpi compiler is not on the path.
