Go ahead and create all the needed sub-projects in Qt Creator. We could envision the following code base structure:
# part2-cute_comics.proTEMPLATE = subdirsSUBDIRS += \ cutecomics/entities \ cutecomics/usecases \ cutecomics/gui \ ccpanels
The main sub-project will be called part2-cute_comics.pro, and should be generated from a Subdirs Project template. Its first three sub-projects (entities, usecases, and gui) should also be generated from a Subdirs Project template, while the last one (ccpanels, short for cutecomics Panels) should be generated from a Qt Quick Application template.
Then, to each of the first three sub-projects, create and manually add a .pri file of the same name; for example:
# entities.proTEMPLATE ...
