Ok I see - part of the root of the problem is you are probably using git rather than a version control system that works naturally with large shared repo's like svn? So it's easier to just have separate repo's - and then that makes sharing code sensibly a nightmare without additional tooling... etc etc because there isn't a single versioning system. Everything as a separate git repo has a lot to answer for in my opinion.
