Another idea would be the following behaviour (also with a policy):
if a file, which has been found via CMAKE_MODULE_PATH or CMAKE_ROOT, includes 
another files, it looks first in its own directory, then in 
CMAKE_MODULE_PATH, then in CMAKE_ROOT.

This would result in the same new behaviour for files in CMAKE_ROOT, 
additionally it would also change the search order for files found via 
CMAKE_MODULE_PATH. So this would be a bigger, but maybe more consistent 
change from the current behaviour.
