Specify the full PATH of your cmake, otherwise the environment will just pick up
the default cmake on the cluster.

There is no point in compiling the whole suite of tools with MPI; nothing makes
use of MPI except mdrun. So if you want to compile all the tools (preprocessing
and analysis), don't set GMX_MPI. If you are using GMX_MPI, then set
-DGMX_BUILD_MDRUN_ONLY=ON to get MPI-enabled mdrun. Strictly speaking, MPI is
not required, but it depends on what you want to do whether or not you need it.
