qt5vsaddin does not properly add new classes to moc output / errors out stating project was not built by qtvs5addin and a QtClass can not be created

Whenever I add a new class, if I add just a c++ class and derive from QObject no equivalent instructions to invoke moc are generated, causing compilation failure. I am unsure off-hand if that's usual behavior or not, however, when I attempt to add a 'QtClass' under qt5 types in the add class dialog underneath the inputs in the dialog box there is a red error message informing me that the project was not created by the qt5vsaddin tool and thus it cannot add new QtClasses.

The project is a 64-bit target, finagled into compiling by doing the conversion to qmake and back (attempted as both project types) process I outlined in the other bug I filed concerning the add-in and 64-bit targets (I don't have the bug number off-hand), so it is at least possible this is a manifestation of the other problem and an improper initialization by the conversion back and forth.
