Okay, I looked at the C++ code of MSYS generator.  And surprise, 
surprise.  It does EXACTLY what I said to do of searching the path (but 
looks for make.exe instead of sh.exe).  Also it uselessly (and somewhat 
potentially incorrectly) parses /etc/fstab to find where mingw's bin 
directory is (and does not cache any of the other paths, which could 
indeed potentially allow FIND_PATH() and others to work with mingw paths 
eventually).

The C++ code just forgets to set CMAKE_INSTALL_PREFIX to MSYS proper 
values.  I'll revert this .cmake patch and I'll give you a C++ patch of 
it instead, as the code is much cleaner that way.  And to be honest, I 
find the C++ code to be much more readable than the .cmake code (which 
is somewhat disturbing).
