Oh yeah. My version was made off of a updated version of that repo by calinou. You will notice that if you read the readme in my repo. And yes, the version you used is out of date and will not build with the modern software. Mine is basically that, but updated so it is buildable (calinou did that part), and then I made it so it can accomodate the latest packages, (from 2020 edition) and it has an installer script. The script installs the necessarry dependencies, builds it, and makes a desktop launcher.

I am really sure it will build, but I remember building it was a bit of a hassle. 😅
Mostly because enet is build with it and there was a tricky part to make that work but I can't remember what it was.
Sadly, I made no notes or a documentation about the building process on Linux. Back then I was so young and was not working in a wise way.
I also have learned over the years that writing documentations and making notes is really useful if you pick up something at a later date ... and I really enjoy writing documentations these days. 😄
