You are wasting your time.

It's not going to be that easy. You will need to replace all the calls
to CMake with generated stuff. Even in the improbable case you
succeed, you would be giving people something which somewhat works,
you would not be shipping the actual buildsystem but some kind of a
pseudo-pre-geneated buildsystem.

Morale: anal retentive people must learn that opening your ass to
something new may make you happier.
