of course i did research before posting my question.
I looked at
How to "add existing frameworks" in Xcode 4?
Adding Framework in Xcode 4
Addin
After adding framework via "Add existing framework"
Project Settings
> Build Phases
Add buid phase
> Copy Files
Frameworks
And that's it.
Another important detail here - you must have the "Runtime search path" to be defined in the projects, it's empty by default.
Something like this:
LD_RUNPATH_SEARCH_PATHS = @loader_path/../Frameworks
