Compiling Opencv Error

The first problem you have which is causing the error is that you need to use OpenCV >= 4.7.0 with CUDA >= 12.0 as texture references were removed in that version of CUDA.

The next problem you will have is that OpenCV DNN module (and possible others) is not compatible with CUDA 12.2 at the moment

### 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)

I would advise you to upgrade to OpenCV 4.8.0 and use CUDA 12.1.
