I suspect we should add that workaround into the eclass. I don't imagine any proper fix is coming any time soon and I don't plan on working on it myself (other than perhaps the workaround).
Thanks for the work-around! I had same issue building qtnetworking with clang-17 and "-Wl,--undefined-version" fixed it.

I don't really see the point in keeping this open so closing as fixed (applied workaround). In a year or so, we'll get the Qt 5 fix and it'll propagate down into Qt5PatchCollection naturally.

Fix was merged in Qt Company 5.15 upstream branch. Now we've got to wait just for 1 year...
