我已经将dlib编译为Xcode并引用了“http://prabhu.xyz/2017/05/29/getting-started-with-dlib-on-ios.html”的网站 我按照网站提到的步骤进行了操作，但收到了错误消息：https://github.com/hsmlee/dlip-error/blob/master/README.md
我试图找到收到错误消息的原因。 我想这意味着我需要安装X11。
所以，我安装了X11。
cmake -G Xcode .. -DCMAKE_INCLUDE_PATH = / usr / X11 / include
cmake --build。 --config Release
我是通过上面的步骤构建的，但是我收到了与上一个相同的错误消息。
您可以查看以下错误句子。
请给我很好的反馈！
