The cache variable projX_DIR points at the directory that contains the 
configuration file (e.g. is not an installation prefix) and will also be 
set by cmake itself if it finds a configuration file.
The environment variables projX_DIR and CMAKE_PREFIX_PATH expect an 
installation prefix.

e.g. setting the projX_DIR environment variable to ~/apps/projX should 
have it look in ~/apps/projX/lib/cmake/<name>* as well.
