We have it too: it's QLibrary and our plugin framework. If you use 
QLibrary("udev"), it will look for libudev.so.

The difference is that we need to look for two different versions, which have 
two different interfaces (albeit very similar). If they were radically 
different, we'd have to abstract via a plugin, like we do for the Connman and 
NetworkManager backends to the bearer manager in QtNetwork.

All third-party libraries must be at most as restrictive as our own licenses. 
Therefore, no libraries with terms restrictive like "free for non-commercial 
use" can be allowed.

Moreover, we try to limit the copyleft libraries to specific modules.

There's always an incentive for that, though I don't see how that follows from 
this topic...
