// 3、使用这条命令后编译成功；
$ sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
编译dlib/examples
$ cd /Users/kokia/kokia_face_detect/dlib/examples
$ mkdir build
$ cd build/
$ cmake -G Xcode ..
$ cmake --build . --config Debug
tip: cmake --build . --config Debug 使用Debug，这样xcode断点才能调试，Release无法调试；
Xcode 调试dlib example
需要的参数，直接拖过去；
