I suppose cmake-gui could translate it automatically.   The cmake-gui is 
Qt which does handle \ as a path.  The problem in cmake is that we don't 
really track paths just strings.   In short, it would be a hard problem 
to fix, but you are welcome to create a patch, but I fear it would be 
larger and error prone.  (In which case it would not be accepted 
upstream.).  I did think the gui automatically changed paths to have / 
in them.  That might be a small fix that could be done.
