Hi Simon

Can you show us the CMake error message ?  
Keep in mind that CMake is case insensitive (ex. RELEASE).  
Make sure your CUDA version supports your Visual Studio compiler (check `nvcc --version`).

Hi Mohamed,

1. clone OpenCV 5 from [https://github.com/opencv/opencv/tree/5.0.0](https://github.com/opencv/opencv/tree/5.0.0)  
git clone [https://github.com/opencv/opencv.git](https://github.com/opencv/opencv.git)

2. I used CMake-GUI from downloaded Qt  
cmake version is 3.30.5

I just input source and binaries location and click Configure  
The error is listed as below

(Attachment err.txt is missing)
