But you can never ever build shared libraries this way (at least not  
on all platform). So in fact A and B are one project as one cannot  
live without the other. Questionable software design, I'd say.

It doesn't. You just think it does because instead of a target name,  
you can also pass basic non-target library names.
Additionally, static libraries are not linked, so that doesn't matter anyway.
