[Cmake] Pruning cache entries

[Miller, James V (CRD)]

Is there any way for CMake to identify cache entries that are not currently being used?
 
As a projects needs change or as people determine better ways to set up a project, the CMake cache
ends up with entries that are no longer being used.
 
One option is to wipe the cache and rerun cmake.  But in a project that has a bunch of settings, this
can be rather painful. So would it be possible for CMake (or some other executable) to print out a
list of the cache entries that are actually used (and more importantly, not used) in generating the
makefiles. Then a user could run through the cache and delete the ones that are not needed anymore.
