I commente the line example in cmakelist file and the problem solved but another error occured

clang: error: linker command failed with exit code 1 (use -v to see invocation) make[2]: *** [tools/caffe/caffe2ncnn] Error 1 make[1]: *** [tools/caffe/CMakeFiles/caffe2ncnn.dir/all] Error 2 make: *** [all] Error 2

It looks like there is a problem with your opencv installation It is recommended to reinstall opencv For example brew install
