Having the same exact issue. I'm also on Lunar Lobster - Ubuntu 23.04

After some digging, the problem appears to be that the flag to treat all warnings as errors has been enabled, but warnings haven't been fixed first. So by default, the code simply doesn't build.

I was able to fix it by specifying -DWERROR=0 as a CMake option
