Manager local repository

I come from Java world. I was looking for Apache Maven alternative in C++ world. I think I found the correct project. I have few questions and have not managed to find an answer.

Is it possible to manage local repository. Let's say, I work on 5 similar but different projects and this project share mostly the same dependencies. Will each project have it's own dependencies stored inside each project or is there a "system" wide (per user) local repository where dependencies are stored?

Is it possible to "publish" only to local folder so other project can "see" dependent block or it has to go over bii internet repository?

Or am I wrong - about how bii works.

Looks nice project. Keep up the good work.
