Comment (by hinder):
Bruno: I just ran into this on Hydra, which is similar to supermuc, and setting MPI_DIR to some directory solves the problem. It is never used, so you can set it to anything.
Erik: NO_BUILD means "don't use a preinstalled version". I would say this is misnamed. There might not be a single directory which corresponds to the MPI installation directory, and both MPI_LIB_DIRS and MPI_INC_DIRS need to be set. In that case, there is no meaningful content to put in MPI_DIR, as it will never be used. You seem to be defending the current system and suggesting that people should not have found it confusing. I find it very confusing.
