Linkage could be improved for packagers.
Over at OpenBSD, we've been trying to provide binary packages for the QT GUI for Audacious. Our extant package only links GTK.
On first glance, it looked like it would be possible for us to use what we call "multi packages", where we build once and the installed files are split into multiple smaller packages.
We had planned on having a package containing only the core functionality, then extra packages containing only the files for the QT and GTK stuff. Then users could install either frontend, or both if they wish.
But it seems that if you build with both toolkits (`--enable-gtk --enable-qt5`), some of the core libraries link QT. For example libaudcore:

Is that right, or have we done something wrong?
Perhaps it is the case that we'd have to use what we call "flavored packages", where we build audacious multiple times and generate (conflicting) packages for each different combination of toolkit choices?

libaudcore does have a hard dependency on QtCore (but no other Qt libs) if you build with Qt support. I think a few of the plugins will also end up linking to both GTK and Qt.
I wish we could have achieved a cleaner split, but it proved to be technically difficult, and is probably not going to happen at this point.
Package "flavors" (e.g. audacious-gtk and audacious-qt) are probably a good option, if having a single package depending on both toolkits is undesirable.

Thanks for the clarification!
