well, those are not sub-libraries but external projects with their own build-system. I have sublibraries in submodules and add them with add_subdirectory and everything shows and is auto-completed correctly.

Thanks. We've been using external projects since some of them are old style CMake, ripe with global variables, but apparently we could've used add_subdirectory for some other libs. I'll keep that in mind for future refactorings and libraries.
