当我尝试在 Ubuntu 14.04 上安装带有 CUDA 7.0 的 opencv 时，它返回相同的错误消息。
我正在使用以下命令运行 cmake
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D ENABLE_FAST_MATH=1 -D CUDA_FAST_MATH=1 -D WITH_CUBLAS=1 ..
但它总是返回这个错误
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_nvcuvid_LIBRARY (ADVANCED)
linked by target "opencv_cudacodec" in directory /home/luss/git/opencv/modules/cudacodec
它确实识别了 CUDA 版本，但是链接它或其他东西时出现了问题。

有谁遇到过类似的问题或知道问题可能是什么吗？
谢谢
答案1
问题是缺少libnvcuvid库，可以通过以下链接解决
sudo ln -s /usr/lib/nvidia-346/libnvcuvid.so /usr/lib/libnvcuvid.so
sudo ln -s /usr/lib/nvidia-346/libnvcuvid.so.1 /usr/lib/libnvcuvid.so.1
这解决了 cmake 错误，之后允许将 cuda 视频编解码器与 opencv 一起使用。
答案2
我也遇到了同样的问题，我也在寻找这样完整的安装过程，
我已经遵循了这两个教程，有两个播放列表，一个用于 OpenCV，然后用于使用 OpenCV 配置的 CUDA 安装。
我建议你删除所有内容，cuda 和 openCV，然后从头开始。先安装 OpenCV，然后安装 CUDA。这样就可以了。
1）OpenCV：https://www.youtube.com/playlist?list=PLS1lqxOwNjObyZ_hngOFPrYsSy-ThwQPg
注意：您可能不必从视频 2 和 3 进行安装。
2）CUDA + OpenCV 配置。 https://www.youtube.com/playlist?list=PLS1lqxOwNjOZbnF_m2g2ZQl3Y0F_NJqvM
