Yeah, that is complicated. I think you can do it with Qt APIs, but I wouldn't
know how myself.


For getting/querying, QFontDatabase is your friend.

For installing a font: if it’s enough to add the font so that your application can use it, then QFontDatabase::addApplicationFont, with a font file you ship separately or as a resource.

There's no API in Qt to install a font file with the system. Your application might not have the privileges to do so, so if you need that, then you’d probably best do that as part of your installation routine.
