opencv - 在 Ubuntu 18.04 上使用 cuda 11 构建 OpenCV-4.0.0

Question

我正在尝试在 Ubuntu 18.04 上使用 cuda 11 构建 openCV 4.0.0。
以下是我的 cmakefile

cmake -D CMAKE_BUILD_TYPE=RELEASE \
  -D CMAKE_C_COMPILER=/usr/bin/gcc-7 \
  -D CMAKE_INSTALL_PREFIX=/usr/local/OpenCV-4.0.0 \
  -D INSTALL_PYTHON_EXAMPLES=ON \
  -D INSTALL_C_EXAMPLES=OFF \
  -D WITH_TBB=ON \
  -D WITH_CUDA=ON \
  -D WITH_CUDNN=ON \
  -D OPENCV_DNN_CUDA=ON \
  -D CUDA_ARCH_BIN=7.5 \
  -D BUILD_opencv_cudacodec=OFF \
  -D ENABLE_FAST_MATH=1 \
  -D CUDA_FAST_MATH=1 \
  -D WITH_CUBLAS=1 \
  -D WITH_V4L=ON \
  -D WITH_QT=OFF \
  -D WITH_OPENGL=ON \
  -D WITH_GSTREAMER=ON \
  -D OPENCV_GENERATE_PKGCONFIG=ON \
  -D OPENCV_PC_FILE_NAME=opencv.pc \
  -D OPENCV_ENABLE_NONFREE=ON \
  -D OPENCV_PYTHON3_INSTALL_PATH=~/.virtualenvs/cv/lib/python3.6/site-packages \
  -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-4.0.0/modules \
  -D PYTHON_EXECUTABLE=~/.virtualenvs/cv/bin/python \
  -D BUILD_EXAMPLES=ON ..

我收到以下错误

我测试了 cuda/cudnn 示例，它们运行良好。
任何帮助将非常感激。

似乎是因为版本兼容性问题。两周以来，我一直在寻找同一问题的解决方案。我试图让 OpenCV-4.2.0 在带有 CUDA-11.1 和 CUDNN-8.0.5 的 Ubuntu-20.04 上工作，但它从未奏效。
阅读@antb52 的评论后，我尝试安装 OpenCV-4.4.0，并且成功了!现在，问题解决了!!!
