OpenCv undefined references


I’ve managed to successfully build some android examples (using Android Studio) but am struggling with the OpenCv ones. I keep getting lots of the following errors:

Error:(22) undefined reference to ‘cvCopy’
Error:(40) undefined reference to ‘cvReleaseImage’
Error:(66) undefined reference to ‘cvConvertScale’

From files such as ofxCvShortImage.cpp and ofxCvFloatImage.cpp

I’ve used the project generator to update the project (selecting Android Studio as the platform).

Does anyone have any idea why ofxOpenCv is not being referenced properly?
