This function is not a part of OpenCV. It must have been manually coded to the cv namespace. With that being said, you will need to provide the code that implements that function. After a quick search, it seems like this is what you want:

https://github.com/BloodAxe/OpenCV-Tutorial/blob/master/OpenCV%20Tutorial/cvneon.cpp

Just take this .cpp file and the respective .h file from this repo and add them to your project.
