It builds, but it fails to load game data files, idk what's causing it. This ^ might be a little mess but at least dependencies are included. result/bin/eternallands official tries to launch the game. One might add dialog kdialog or gnome.zenity to runtime dependencies as it can be used to launch graphical dialog which asks which server we want to use. Good luck and have fun 🙂
