@jens55 you are correct, automated builds are already available.
Here is a more direct link for anyone else: https://github.com/FreeCAD/FreeCAD/releases/tag/0.19_pre
I did actually find this page earlier, however I looked at the date the 0.19_pre release was published on GitHub (November last year) and I assumed it was out of date! However the assets attached to the build are the latest version. I should have fully read the page 
I'm guessing @arhi made the same mistake.

Now that Fusion is changing it's license for personal use (what did I expect from "cloud" software) I'm going to be giving FreeCAD another shot. I tried it about 4 years ago but ended up frustrated, however I was very new to CAD in general back then. It looks like some decent improvements have been made and hopefully others who are moving away from Fusion will look to open alternatives - that can only help speed up development.
I'm going to investigate what it would take to setup a build server, could make for a fun little project.
Awesome work, one day I wish to build a machine similar to this. What style of motion system have you selected for this printer?
