Yeah I would do it the way Marcel proposed.

First of all, using file(GLOB ...) to collect lists of files to process
is not a best practice because CMake then can't know if you've added or
removed files from this list and can't know if it needs to reprocess
your CMakeLists. Check the docs for more info.

Either way, if you know what those .so's are (and you obviously do since
you're going to build them), just add those names to your list of
libraries. If you just use the target name ("libfoo", not
"/path/to/libfoo.so"), CMake will figure out the path and any suffixes
or other shenanigans for you.
