There is only one sourcefile that is too big. But it is WAY too big. I'd say 
that, depending on the data, can reach a few thousand files.

Yes, that is what I want to do. The problem is how to do it!
All the ideas I have require me to run cmake twice: first to generate the 
source files, then to glob for them or find them in some other way.

The alternative is running a script. But then I would be using an inferior 
tool to do half of CMake's job.
