appimage issue and solution

There was a problem running the v1.60 appimage of OCVvid2fulldome, created in mid-2020 on Ubuntu 18.04, when trying to run on Linux Mint 22 (based on Ubuntu 24.04). 

AppImage: symbol lookup error: /lib/x86_64-linux-gnu/libgio-2.0.so.0: undefined symbol: g_module_open_full

Probably this is related to

https://github.com/AppImage/AppImageKit/issues/1162

- a solution is mentioned at 
https://github.com/probonopd/linuxdeployqt/issues/526#issuecomment-1911779101

So, opened an issue. But found that simply creating an appimage with Ubuntu 20.04 solves the problem.
