compile dlib on mac os

I compiled the dlib c++ code on macOS.This is the result when I type cmake

build cmake ..

It seemed work well for me.Then I did 

cmake --build . --config Release

It looked like everything is done.But when I tried to run the example like this

./face_landmark_detection_ex

I got this error.

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

Could someone help me please?

I solved this problem by upgrade the cmake. Last cmake version is 3.5, and the current cmake version is 3.8. But I don't exactly know why upgrading cmake can solve this problem. Could someone tell me the reason?
