Perhaps that's how it's supposed to work, but I'm not intending to mess
around with the target output paths in cmake. It simply makes no sense to
me.

That doesn't work as it's not a static plugin. However this put me on the
right track (or at least I believe it is). Adding this to main():

extern void Q_DECL_IMPORT qml_register_types_Tsc_Ui();

qml_register_types_Tsc_Ui();

Did load the resources properly and I can see the QML module is loaded
(after also adding the import path to ":/")

So is this the "correct" way to do it with my setup with NO_PLUGIN,
then? I can live with the manual call, I'm just wondering if that's
the way.
