I’ve been following the Install from Source guide and by following it exactly I get this at the end of my cmake:

I’m on a pretty much fresh Linux machine. I’ve tried messing with the llvm config by removing some of the arguments.I also tried installing clang in the conda environment and specifying it as the compiler in Cmake, but it gets overwritten as the C compiler and causes an infinite loop. Do you guys have any insights on this issue? Thanks so much.
