The problem comes up once in a while. And the argument for why this doesn't 
work is that you cannot link static libraries into another. Well, then don't, 
I'd say. CMake knows the names of the object files to link into the final 
library, it just needs a frame to let the CMake user work with it. One could 
be a VIRTUAL key word for add_library that makes it just a place-holder for a 
group of object files: no link stage. When such a "library" is linked to 
another, well... obvious...
