Part of the reason the compilation was taking forever was because I was building OpenCV for Java. I learned this after my build completed successfully and I was unable to locate the python package. I ran into some issues with the CUDA toolkit 12.9, so I downgraded to 12.8. I also downgraded the NVIDIA Video Codec SDK to 12.2. The build fails with OpenCV world enabled, so I just hit rebuild for the Nth time today. Will report back tomorrow.
