KDevelop's parser already has internal support for preprocessing.  Because we 
want to offer incremental parsing (so that hopefully processing can be done 
real-time, or as close to it as possible), we really need to have this 
control ourselves.

One thing which will be crucial to code completion etc. is the information 
that cmake uses to invoke gcc, eg. include directories, command line defines 
(-Dblah=foo), etc.  I'm hoping that Matt's cmake integration will be able to 
pick all of that out.  Once that's done, getting an api created and submitted 
to cmake will be important for maintainability.

Cheers,
Hamish.
