OK, I merged that PR to make it easy for people to turn off the OpenCV, even if it's found.
The only way the OpenCV is used is to provide interoperability with OpenCV. So if you're not using them together, you won't really miss anything by disabling it entirely. (That's a *slight* lie. ImageBufAlgo::capture_image uses OpenCV. But almost nobody cares about this.) > On Jul 25, 2015, at 6:12 AM, Sebastian Schoellhammer > <[email protected]> wrote: > > Hello again, > > thanks so much for the replies.
