I know Ubuntu is a choice for many developers but I've been a Fedora guy for decades. It's always been such a pain to get a nicely integrated cross-compile environment going with Qt Creator on native Fedora.

For anyone out there who has been feeling the same pain, here you go!

It's a full Yocto which produces both an image for RPI and a cross-compile SDK which actually works on Fedora 42.

Includes Qt 6.10.3 in the SDK and all the goodies including QMqtt and QSerialBus.

The README contains instructions for kit creation.

Although the easiest way is to source the SDK environment, I was able to tweak my kit so that was no longer necessary (you can just start Qt Creator from the desktop and get building code).

I hope this helps any other Fedora running Qt lovers!
