[CMake] How to generate preprocessed file?

[Marcel Loose]

Thanks,

I didn't know it was that simple. The thing is that I ran 'make help' in
the top-level build directory and it didn't show any .i target. However,
after I descended into the build directory of the actual source I *did*
get to see these .i targets. Wonderful!

Best regards,
Marcel Loose.
