Try the new qt based cmake-gui, it does not do that.

The CMakeSetup will be deprecated in the next release, so no need to fix it.

That sounds good.  A lot of the modules need a bit of work....  Ideally 
you should not have to list many PATHS at all.  CMake does look in some 
common places automatically.   Many of the Find modules have not been 
update to reflect those changes that were made to cmake.
