如何在python的setup.py中调用cmake构建python库的插件

# setup.py

from setuptools import setup, Extension
from setuptools.command.build_ext import build_ext
import sys
import os
import setuptools

class CMakeExtension(Extension):
    def __init__(self, name, sourcedir=''):
        super().__init__(name, sources=[])
        self.sourcedir = os.path.abspath(sourcedir)

class CMakeBuild(build_ext):
    def run(self):
        for ext in self.extensions:
            self.build_extension(ext)

    def build_extension(self, ext):
        extdir = os.path.abspath(os.path.dirname(self.get_ext_fullpath(ext.name)))
        cmake_args = ['-DCMAKE_LIBRARY_OUTPUT_DIRECTORY=' + extdir,
                      '-DPYTHON_EXECUTABLE=' + sys.executable]

        build_args = []
        os.makedirs("build", exist_ok=True)
        os.system(f"cd build && cmake .. {' '.join(cmake_args)} && cmake --build .")

setup(
    name='mylib',
    version='0.1',
    ext_modules=[CMakeExtension('c_lib')],
    cmdclass={'build_ext': CMakeBuild},
    zip_safe=False,
)
