MacOSX10.14 Build Errors in CLM.cc

[Andy-2S]

When building on macOS , I'm getting the following errors from CLM.cc related to not finding copy constructors.

Use cvIplImage(im) and if you get this error error: no viable conversion from 'cv::Mat' to 'CvMat'
You can use cvMat(wimg)
Check my project if you get the other error.
