This does not expose the actual command called when linking, expect
something started with gcc/g++.

I don't know where's the actual code and packaging stuff that you are
currently working on, but some CMake program uses
TARGET_LINK_LIBRARIES to generate a target, and you can add libraries
there. But it's not for all, some more skilled CMake users may use
more advanced way of linking.
