Use SWIG to wrap OpenCV's C++ API in GO

Question

I'm trying to use SWIG to wrap OpenCV's C++ API. For now, I have system-wise OpenCV installed. My questions are:

1. Is it possible to wrap "system-wise" library without putting them into the same directory of my SWIG files? For example, my opencv's header files are in /usr/local/opt/opencv/opencv2/opencv.hpp . Can I use %include "opencv2/opencv.hpp" in SWIG?

2. How should I start with this work? Should I wrap the CONSTANTs first?

thanks.

You can %include any header file you like. It doesn't have to be in the same directory.

I would start by thinking about the API you want to present to Go programs. A good Go API is often different from a good C API.
