Nvidia 2070 Super supported for OpenCL?

[Gilles Caulier]

Hi,

Under Windows we package with an older release of OpenCV framework in
charge of to deal and to use the GPU for the computation. This is
probably the problem. This is due to a UPSTREAM bug in the VCPKG
package manager.

best regards

I checked the docs but could not find a reference to these environment variables. I found this note online (https://discuss.pixls.us/t/opencl-not-showing-in-digikam/49711/4) suggesting that adding "OPENCV_OPENCL_DEVICE=NVIDIA:GPU:" might correct the issue.
