[CMake] Source code configuration management in CMake?

[Ian Scott]

Thanks for the suggestions.

I've decided to do inside our subversion repository, since I need to 
maintain a branch for this project anyway. There is no point scripting 
the cutting down since I only have to do it once, carefully, on the 
repository branch.

Thanks again.
Ian.
