From what I know, such builds require a script. I think that they are more common within large open-source projects (e.g. to quickly detect bugs introduced by some developers). FreeCAD has weekly builds.
If it’s too troublesome to maintain in the case of PrePoMax, I think that builds like those made by Ihor Rokach whenever the source code on GitLab is updated (last build is from 18.09 but he has always been updating them regularly) can be sufficient: PrePoMax
Even if Ihor doesn’t build PrePoMax for us, he shared an instruction explaining how to do it: CMD-script for automatic PrePoMax compilation so we could try building ourselves so that Matej doesn’t have to worry about it.
