找不到文件cuda_runtime.h

在windows 11系统，opencv4.1.2+opencv_contrib+Qt5.15.2的环境下，添加了cuda的include、bin、lib的环境变量，但是仍然出现以下问题。

In file included from E:\src\opencv_contrib-4.1.2\modules\cudaarithm\src\lut.cpp:7:
E:\src\opencv_contrib-4.1.2\modules\cudaarithm\src\lut.hpp:10:10: fatal error: cuda_runtime.h: No such file or directory
 #include <cuda_runtime.h>
          ^~~~~~~~~~~~~~~~
compilation terminated.

解决：
找到cuda_runtime.h的绝对路径，把此处的#include <cuda_runtime.h>改成#include <C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.8/include/cuda_runtime.h>

找不到boostdesc_bgm.i

E:\src\opencv_contrib-4.1.2\modules\xfeatures2d\src\boostdesc.cpp:654:20: fatal error: boostdesc_bgm.i: No such file or directory
           #include "boostdesc_bgm.i"
                    ^~~~~~~~~~~~~~~~~

解决：下载这个文件，解压到这个目录opencv_contrib/modules/xfeatures2d/src/

找不到features2d/test/test_detectors_regression.impl.hpp

E:\src\opencv_contrib-4.1.2\modules\xfeatures2d\test\test_features2d.cpp:51:10: fatal error: features2d/test/test_detectors_regression.impl.hpp: No such file or directory
 #include "features2d/test/test_detectors_regression.impl.hpp"
          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

解决：将opencv / modules / features2d复制，然后粘贴到build目录中来解决该问题。
