Incorrect python env setup for macOS in workflow #7
Description
Generating python bindings via pip install . fails for macOS in test workflow. This is due to incomplete environment setup in .github/actions/setup-python-env/action.yaml. The problem is that shiboken cannot find clang and falls back to v0.64 , which fails to generate the python bindings.
We must add a new step, only for macOS, which will complete the clang setup and help shiboken find it.
