[Bugfix] Pass PYTHONPATH from setup.py to CMake #7730

In clean build environments such as cibuildwheel, build dependencies are installed in a virtual environment located at /tmp/pip-build-env-xxx. This path is in the PYTHONPATH of the setup.py file, but it is not passed to CMake and subsequent Python calls. This PR fixes this behavior by passing the PYTHONPATH from setup.py to CMake, and finally to the machete/generate.py script (which uses jinja2 from build dependencies).

👋 Hi! Thank you for contributing to the vLLM project.
Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which consists a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of default ones by unblocking the steps in your fast-check build on Buildkite UI.

Once the PR is approved and ready to go, please make sure to run full CI as it is required to merge (or just use auto-merge).

To run full CI, you can do one of these:

  • Comment /ready on the PR
  • Add ready label to the PR
  • Enable auto-merge.

🚀

Thanks for the PR, this seems reasonable. FYI @LucasWilkinson just because it involved machete
