Hi, I don't think I've ever seen a direct answer to this question. Is it something to be decided on a case by case basis? If so, then why is there no general case?
I can see a possible reason that it is not solvable in the general case because sometimes the behaviour of find_package can be changed by setting variables (eg, one might use QT_USE_QTXMLPATTERNS before finding Qt4). Specifically this comes up for me because I need to know whether Qt5 modules should find their own dependencies. That is, should find_package(Qt5Gui) cause find_package(Qt5Core REQUIRED) to be called or not? Should that be the responsibility of the caller?
