Something like PCH support is a native build feature that CMake should 
support.  As such, it should be done in C++, and built into CMake.  Some 
work has been done to support this.  The "hard" stuff for CMake should 
be done in C++.   That is the implementation language of CMake. 
Ideally, there would be a few commands you would call to enable PCH's in 
a cross platform way.   Brad King has looked into this, and because it 
is done so different with so many compilers it is hard in any language. 
If you really are interested in adding support for this, I would 
recommend you work with Brad and try to pick up where he left off.
