Compiling opencv4.5.5 with CUDA (4.2.0+cuda11.1+cudnn8.0.5 failed)

I haven't won a prize for living so big , Never hit more than 20 A $lottery , I won a prize in this place , Very sharp ！！
Finally change to 4.5.5 The version succeeded :

cmake The content of :

brothers , The benefits have been paid , Trampling on numerous pits .cache file :

– From Baidu network disk super member v5 The share of
Permanent validity ！
Cry , In memory of my dead brain cells ！

Test whether the compilation is correct :

Code :

#include <iostream>
#include<opencv2/opencv.hpp>

int main(int argc, char* argv[])
{
    
    cv::cuda::GpuMat img(400, 600, CV_8UC3, cv::Scalar(255, 0, 0));
    cv::Mat cpuImg;
    img.download(cpuImg);
    cv::imshow("test", cpuImg);
    cv::waitKey(0);
    return 0;
}

I don't trust you, but I made a match again

after work , after work ！！

When I left yesterday g++ Compile successfully , however vscode Call failed , Mainly cv::cuda:cvtColor function , Today is OK

stay task.json Medium plus lib library , current task.json Long like this

    "tasks": [
