How to compile on Linux?

Dear,

What is the recommended method to compile from source? I've tried g++, using Qt and also Qmake, none of that is working without all of them throwing numerous errors. Running Linux Mint 21.3. I did check Issue #2 (closed) #2 (closed) which does not seem to have any useful hints in that regard (recommended compile method), although I did clone using $ git clone --recurse-submodules after reading through.

Kind regards
