It looks like CUDA support is **NOT** compiled into the OpenCV 4.1.1 build in Jetpack 4.4 DP [L4T 32.4.2]. Is that intentional? ---

You may have a part of the answer in this topic: > [@Is there a plan on next Jetpack release for opencv (cuda) support?](https://forums.developer.nvidia.com/t/is-there-a-plan-on-next-jetpack-release-for-opencv-cuda-support/120608/3): > > I think it’s mainly a QA topic. Opencv’s test suite can have hundreds of tests per module. Although many improvements are made from hundreds to a few tests failing, as far as I’ve been able to check a few weeks ago with a pre-4.3 version, not all are yet perfect and if one among the many tests failed, it would report the module as failing, even if this is just a corner case. I don’t know about NVIDIA’s QA requirements, it may be less or more restrictive… Someone else may better comment. ---
