You can't, too much depends on the compiler, that is why CMake plays it
safe and clears the cache. If you were reading the output, it actually
tells you so. And when building ParaView you don't need mpic++ in the
first place, CMake knows how to include/link with MPI without the help
of these wrapper-scripts.
