Hi everybody. I' m packaging digikam(https://digikam.org). A free photo management software from KDE project. There're 2 dependecies missing from current Guix(qtav & libksane) I tried to package qtav(https://github.com/wang-bin/QtAV/) first, but it's latest release(v1.13.0) failed to build with Qt 5.14. And it was fixed in https://github.com/wang-bin/QtAV/commit/5abba7f0505e75fc. The question is: "Should I backport this fix to v1.13.0 or just use this commit to build qtav?" If there're some guidelines on this, please tell me, thanks a lot! -- Zihao
