我尝试以这种方式使用cgal-swig绑定：我安装了cmake 3.17.0和brew
>>brew install cgal
>>brew install swig
>>cmake -DCGAL_DIR=/usr/local/lib/cmake/CGAL -DBUILD_JAVA=OFF -DPYTHON_LIBRARIES=/usr/local/bin/python3
然后我得到了以下内容：
cmake -DCGAL_DIR=/usr/local/lib/cmake/CGAL -DBUILD_JAVA=OFF -DPYTHON_LIBRARIES=/usr/local/bin/python3
CMake Warning:
No source or binary directory provided. Both will be assumed to be the
same as the current working directory, but note that this warning will
become a fatal error in future CMake releases.

之后我在终端中运行：>>制作

之后，我在python中运行了一个测试文件，得到了以下错误：

我尝试了Can'；升级到莫哈韦后，我无法在Mac上编译C程序，但这并没有帮助：
>> open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
以以下方式构建cgal-swig绑定时也是如此：
git clone https://github.com/cgal/cgal-swig-bindings
cd cgal-swig-bindings
mkdir build/CGAL-5.0_release -p
cd build/CGAL-5.0_release
cmake -DCGAL_DIR=/usr/lib/CGAL -DBUILD_JAVA=OFF -DPYTHON_OUTDIR_PREFIX=../../examples/python ../.
我希望有人知道问题出在哪里，或者建议检查哪些东西？
我安装了带有brew的python，并遵循https://github.com/davisking/dlib/issues/889包括这个
>>>cmake -DCGAL_DIR=/usr/local/lib/cmake/CGAL -DBUILD_JAVA=OFF -DPYTHON_LIBRARIES=/usr/local/lib/python3.7 -DPYTHON_LIBRARY=/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7/lib/libpython3.7.dylib -DPython_FRAMEWORKS=/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework -DPYTHON_INCLUDE_DIR=/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Headers
这对我有用！
