For those using Windows mostly,
It’s now possible to do pretty decent development for JUCE Linux under Windows 11.
With Windows 11 they’ve enabled wslg (I believe it can also be enabled for Windows 10 but not officially)
The only major block is still reading files from Windows file-system being slow (I need to search about that as there might be some things to speed it up).
But still it’s quite nice being able to cross-build Linux without too much fuss on Windows machine.
