Do a search and see how many topics there are on this forum about compiling OpenCV for Jetson. Or a web search, and see how many articles have been written with different solutions to this same problem.
Why does the official JetPack ship OpenCV without CUDA? How many tens of thousands of hours over the last couple years have been wasted by the community because this extremely obvious dependency doesn’t come precompiled in JetPack or on the L4T apt repositories?
Honestly, this is a “why” question. Why doesn’t NVIDIA ship NVIDIA-optimized components with JetPack, and instead requires the community to spend countless hours 1) figuring out HOW to compile 2) actually compiling, which literally takes hours?
