Unsupported Wheel on x86_64 Intel Chip Mac running OSX 13.4

I have a working CMakeLists.txt file which generates both an executable (racplusplus_exe) and a static library (racplusplus.cpython-311-darwin.so) wrapped with pybind. The executable runs perfectly, and I can import the static library in python and run functions successfully.

When I use setup.py to python3 setup.py bdist_wheel I get a wheel built in dist/racplusplus-0.9-cp311-cp311-macosx_13_0_x86_64.whl. But whenever I try to pip install the wheel I get the error "ERROR: racplusplus-0.9-cp311-cp311-macosx_13_0_x86_64.whl is not a supported wheel on this platform."

During the build output I see multiple lines with mention macosx 10.9 for some reason. ie: "installing to build/bdist.macosx-10.9-x86_64/wheel". So I wonder if somehow the wheel is being built for the wrong macOSX, even though the final wheel name has the correct OS?

I have tried manually setting

python os.environ["ARCHFLAGS"] = "-arch x86_64 -mmacosx-version-min=13.0"

and also manually setting

python os.environ['MACOSX_DEPLOYMENT_TARGET'] = '13.0'

in "setup.py", but neither of these environment variables seems to be respected.

Any ideas what's going on? Not sure this is inherently an issue with setup.py for newer OS's or if I'm not understanding how to specify the wheel architecture correctly.

CMakeLists.txt と setup.py を使い、python3 setup.py bdist_wheel でビルドを再現し、その後 build/bdist.macosx-10.9-x86_64/wheel の出力と MACOSX_DEPLOYMENT_TARGET および ARCHFLAGS の設定を確認する。生成された wheel タグをインストール先のプラットフォームと比較する。指定された macOS x86_64 環境に wheel を正常にインストールできれば完了とする。
