我的目标：
我的目标是配置 OpenCV 4.5.1-dev 的构建，支持 cuda、tesseract 和 QT，而不会出现任何 cmake 错误。
我遇到的问题：
当我按下 cmake gui 上的配置按钮时出现以下错误：
CMake Error at modules/dnn/CMakeLists.txt:39 (message):

尝试解决问题
错误：CUDA 后端需要 cuDNN。请解决依赖或禁用
尝试解决问题：
- 将 Cmake 选项指定为
CUDA_ARCH_BINcuda sdk (11.2) 的版本。我认为标志是关于 cuda dnn 版本的 - 为我的 gpu 计算功能（版本）指定了 cmake 选项
CUDA_ARCH_PTX，因为我认为它是关于Compute capability (version). 根据这篇维基百科文章，我知道我的计算能力是什么 - 我尝试按照在此线程中找到的 AbdelAziz AbdelLatef 的说明进行操作： 如何在 C++ 中处理“DNN 模块未使用 CUDA 后端构建；切换到 CPU”警告？但是它并没有帮助，因为已经启用了 cmake 标志，并且我已经将 opencv contrib 添加到了我的 cmake 配置中
- 我尝试指定 CUDA_ARCH_BIN 标志来
6.1喜欢这个 关于 opencv 问题的问题评论，就像我指出的那样。按照他所说的，说我仍然有错误。
