Let's say I have Qt workspace which contains two projects. In the root directory I have .pro file with TEMPLATE=subdirs and SUBDIRS=Server Client
Now I want to create common Include directory, which contains h-files used by all projects. I want to see these h-files in Qt creator. How can I do this? For example, I can add Include to SUBDIRS, in this case I need to write some kind of "do nothing" .pro file in the Include directory.
