Need cross-platfrom CI or at least a way to ease releases

[ttdm]

This has been an issue for a while.

I've been using windeployqt on windows, which is an OK solution but still forces me to use a windows machine with QT on it (which isn't that easy to me at the moment).

I've been using travis CI and probonopd solutions for linuxAppimages but his solution doesn't work with QT6 and travis CI switched to QT6.0 9month ago if i recall everything properly. So this worked for a year but doesn't work anymore.

I've been able to access a mac once to and create an App once but I have absolutely no solution for it.

To make it clear, at the moment, i have :

• a troublesome, not practical, but manageable solution on windows
• no solution on linux
• no solution on macOS

Any help is appreciated.
