My fork on github has an action on the restructured branch https://github.com/poetaster/Subsoniq/tree/harbour the action is in the .github/workflows folder.
It’s currently failing because of a missing dependancy, also from Znurre:
QJsonSerializer which is in another repo but I haven’t tried building yet:
https://github.com/poetaster/Subsoniq/actions/runs/11709674258/job/32614220788#step:4:71
I’d be happy NOT to work on this 
EDIT: restructuring was required to pull the rpm directory into scope for the action which is based on @coderus containers.
