[CMake] Joining an OBJECT and a SHARED library

[Robert Maynard]

I believe what you are looking for in the CMake 3.12 improvements to
object libraries. In 3.12  the target_link_libraries command now
supports linking to an object library to embed the object files ( only
on direct dependencies, no propagation of .objs ) and also propagates
usage requirements like any other library.
