If you can I would use CUDA 12.1 until the below is fixed

### System Information OpenCV version: 4.8.0 OS: Windows 11 Compiler: Visua…l Studio 2022 CUDA: 12.2 ### Detailed description Switching from CUDA 12.1 to 12.2 results in several compilation like the one below when compiling the **dnn** module. <details> <summary>D:\repos\opencv\opencv\modules\dnn\src\layers\../cuda4dnn/primitives/normalize_bbox.hpp(114): error C2666: 'operator !=': overloaded

API's](https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html#cuda-math-release-12-2) being reworked in this version of CUDA, specifically changes to the `C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.2\include\cuda_fp16.hpp` file. ### Steps to reproduce ``` cmake.exe -BBUILD_DIR -HOPENCV_DIR -GNinja -DOPENCV_EXTRA_MODULES_PATH=OPENCV_CONTRIB_MODULES -DBUILD_opencv_world=OFF -DWITH_CUDA=ON -DCUDA_TOOLKIT_ROOT_DIR="C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v12.2" -DCUDA_ARCH_BIN=8.6 cmake.exe --build BUILD_DIR --target opencv_dnn ``` ### Issue submission checklist - [X] I report the issue, it's not a question - [X] I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution - [X] I updated to the latest OpenCV version and the issue is still there - [X] There is reproducer code and related data files (videos, images, onnx, etc)

Thank you, it is ok to recover to CUDA 12.1.
