Can't really help with exact instructions for other distros, but the "in a nutshell" is you need to install qtcreator and QT5.
After you have them installed and working all you have to do is load the .pro file from the Project directory (https://github.com/TheBeef/WhippyTerm/tree/main/Project) you should be able to just hit the green debug/go button and it should work (you do need to be using the gcc toolchain). This is the same for the Windows build.

Hope this helps.
