Hi Chris:

I haven't used it myself that way, but my understanding is CMake deals
well with the issue of building extremely large sets of interdependent
software libraries. I therefore suggest you take a look at some large
software projects (e.g., KDE and/or VTK, but perhaps others here have
additional examples) to see how those software projects organize their
builds with CMake.  That may give you some ideas on how to avoid the
build issue you have discovered for the current way you organize the
build of your interdependent set of libraries.
