This is not exactly what you want, but may contain the solution you
need. I wrote 3 articles on getting separate projects to build
together as if they were one. The articles partly focus on the issues
of getting Git and Mercurial to cooperate with this, but also use
CMake as the glue. (I invent the name 'Unification script'.) I use
LuaDoc as the real world example which has dependencies on a bunch of
other projects.
