I can't seem to get cmake to recognize GMX_ACCELERATION=BlueGene with git head.

The dearth of general online documentation about cmake makes life difficult, but I thought

CC=blrts_xlc CXX=blrts_xlc++ GMX_ACCELERATION=BlueGene cmake

should be sufficient. If not, what should I be using?

Can we have a (draft) set of cmake building instructions for git master for those of us who are not (yet) cmake-fluent, please?
