Ah, I see, you mean that the external configuration step of OpenCV requires OpenCL by default? As you already said that you can manually switch it off in the OpenCV-build, it should be possible to set the variable through our CMakeExternals/OpenCV.cmake file. I'll forward your mail to our internal OpenCV users. Best, Stefan

I expressed myself in a wrong way (put OpenCV where I meant OpenCL) in the body of the email (the title was right): OpenCV is requesting OpenCL to be installed in your system. If it does not find it, it fails. A workaround is configuring the ep OpenCV and manually disabling the required OpenCL. I haven't traced back since when this in happening, but in a previous commit (late in August), it did not happen. Thanks!

I'm just built the latest master version and I have found that OpenCV activated OpenCV by default. Since I do not have support for OpenCV in my machine, the build fails. Is it possible to change this OpenCV default behaviour? Thanks! Federico
