Did the Experimental ever finish?

The non-optimized cmake might be that much slower.  It is doing lots of 
stl string stuff, which in debug or non-optimized mode can be very slow. 
  However, I suspect it is just the shear volume of output that is 
causing the trouble.

Xcode is very very verbose, and CMake looks at every line of output.  I 
will investigate some more and see if there is something that can be done...
