Question

我在macOS上编译了dlib c ++代码。这是我输入cmake时的结果

build cmake ..

这对我来说似乎很好。然后我做了

cmake --build . --config Release

看起来一切都已完成。但是当我试图像这样运行这个例子时

./face_landmark_detection_ex

我收到了错误。

dyld: Library not loaded: libmkl_rt.dylib
  Referenced from: /Users/fengshaozhe/Applications/dlib-19.4/examples/build/./face_landmark_detection_ex
  Reason: image not found

有人能帮帮我吗？

我通过升级cmake解决了这个问题。最后一个cmake版本是3.5，当前的cmake版本是3.8。但我不知道为什么升级cmake可以解决这个问题。有人可以告诉我原因吗？

在mac os上编译dlib
