I think this is just a problem with a missing static-compiled version of
Qt5X11Extras.  If you don't have a static Qt then I would think you
would have run into error messages earlier though.  If you compiled your
own Qt to make a static version of it then you may have missed that
Qt5X11Extras is part of a separate module, it's not part of the qtbase

There are various technologies out there to try to solve distribution of
application binaries on Linux without a full-blown container
infrastructure like Docker, including FlatPak, Snappy, and AppImage.

I've never used any of those however and so I'm not sure how easy it is
to use, but something in that category seems like the best bet IMHO.
