As long as Breeze itself doesn't have a hard dependency on ≥ Qt 5.13, you'll need to handle that case, and make sure the added code either still works for 5.13 or gets# ifdef'd out. ...Or you could bump the dep to Qt 5.13, but that's probably not feasible given the relative recency of its release and the fact that it's distributed with Plasma, which is not bumping the Qt dep that high.
