Possibility to automatically add fypp preprocessing step

[bhourahine]

Excellent project!

Would it be possible to add the option for a fypp (or other processor) step to the build system, if supported by the build system?

In theory, yes, it would be possible to add preprocessor as well. However, only CMake can deal with it currently from the supported build systems, so for the other two, selecting that option will not have any effects...

Yes, inclusion would of course have to be build system dependent. But it is a good way to further enhance projects using the cookie cutter templates (and encourage correct fypp use in the cmake workflow).
