OpenLara core lost?

Hello, I wanted to put this core, which, although it has some bugs, worked, but I realized that it no longer compiles for some reason.

Let's see if someone looks at it and puts it, because it's a shame. Missing fixes and stuff, but it seems like it was abandoned or some problem with the code, but it's weird that nothing is said.

Let's see if anyone knows what happened.

Thank you.
