Out of source build would not work this way if the build directory is
outside of the source directory. I don't think that it is acceptable.

I'll rewrite my solution to CMake to don't spread logic across files.

It would be nice in theory, but it would require quite accurate handling
of paths that contain spaces. Likely IFS redefinition and so on. I would
not step into this until there will be a real need, but rather provide a
simple wrapper that works always.

Anyway, now everything in CMake (see patch v2).
