To reproduce

brew install ninja
git clone https://github.com/microsoft/ShaderConductor.git
cd ShaderConductor
python ./BuildAll.py Ninja clang

Additional context

❯ sw_vers

Also had to change BuildAll.py as such:

Created #68 for the Python script.

You can comment out this line in the CMakeList.txt

set(${flagVar} "${${flagVar}} -march=core2 -msse2")

Than I was able to compile it. But the Lib is still only build for x64 and I was not able to link it with my arm64 code.

Hi Douglas Lassance (@douglaslassance) I have a working build. Here is my diff pinguin999@08d2ff1
