Hello.

I could not compile the sddm display manager because the qt5_use_modules
macro is deprecated.

So I made this patch which is based on the sddm upstream patch
<https://github.com/sddm/sddm/pull/1024/files/7ac4e53c814e405fceade0fa75366c092a521c32#diff-af3b638bc2a3e6c650974192a53c7291>
.

Stefan.
