Qt5 build support

[EndrII]

Hi @EndrII, thanks for the quick response. I'm unable to build with Qt5 on commit 3731aec. Have you stopped supporting Qt5?

I also tried installing Qt6 as suggested in the docs using: sudo apt install qt6-base-dev But the build still fails. Perhaps I’m missing some other required packages—my bad if that’s the case.

Yes, the quasarapp library depends on Qt6.
I will add support for Qt5 later.
