Unable to build for Portal on macOS

[Duarte475]

Hi, I'm trying to build the source engine so I can play Portal on my M1 MacBook. I configured waf with the command python3 waf configure -T release --prefix='' --build-games=portal I tried building with python3 waf build but it error out with:

Waf: Leaving directory `/Users/duarte/source-engine/build'
Build failed
