 # --compile option compiles Python source files to bytecode
 # --disable-pip-version-check is useful in offline scenarios to avoid a query to PyPI
-# --no-use-pep517 is necessary for compatibility with older setuptools on centos stream 8 and 9

-# --check-build-dependencies option cannot be used here since centos stream versions 8 and 9 don't support it
-# --no-build-isolation by itself would also skip PyPI downloads, but centos stream 8 and 9 have older setuptools which is buggy
