I'm understanding more... but there is still something I don't understand.
Don't the moc_*.cpp files get compiled directly too? How does qmake know
not to generate Makefile instructions to directly compile the moc_*.cpp
files that use Q_PRIVATE_SLOT? If it were to compile them directly, it
would be missing the private headers, which was the error I was seeing.
