After adding some missing dependencies and running qmake/make/make install, I was ready to try it out using my old profile from windows.
It started just fine, but I was missing my map and all labels/miniconsoles. Turns out that Geyser wasn't loaded, and that was because I was missing some lua libraries.
After some time on google it turned out ok though. Basically I just needed to install community/luarocks5.1. From luarocks5.1 I could then install the missing lua modules:
lrexlib-pcre 2.8.0-1
luafilesystem 1.6.3-2
luasql-sqlite3 2.3.0-1
luazip 1.2.4-1 (The latest version of luazip didnt compile, so I had to use 1.2.4-1 instead.)
After that my profile seems to work the same as under windows.
