OpenCV3.2安装+CUDA9.2

1.首先在解压完的目录下新建build文件夹

2.安装依赖库

sudo apt-get install build-essential libgtk2.0-dev libvtk5-dev libjpeg-dev libtiff4-dev libjasper-dev libopenexr-dev libtbb-dev

3.然后进入到build文件夹右键打开终端

 cmake -D CMAKE_BUILD_TYPE=bulid -D CMAKE_INSTALL_PREFIX=/usr/local -D CUDA_GENERATION=Kepler ..

4.如果遇到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_nppi_LIBRARY (ADVANCED)
linked by target "opencv_cudev" in directory D:/Cproject/opencv/opencv/sources/modules/cudev

可以参考这篇神作：https://blog.csdn.net/u014613745/article/details/78310916

5.如果有遇到-- ICV: Downloading ippicv_linux_20151201.tgz... CMake Error at 3rdparty/ippicv/downloader.cmake:73 (file): file DOWNLOAD HASH mismatch

或者

在此过程中会出现下载 ippicv_linux_20151201.tgz 或者 protobuf-cpp-3.1.0.tar.gz 包失败的情况，若 下载失败 或者 file DOWNLOAD HASH mismatch

可以去https://github.com/opencv/opencv_3rdparty/tree/ippicv/master_20151201/ippicv下载相应的包然后

参考这篇文章的做法：https://blog.csdn.net/youngpan1101/article/details/58027049

6.在完成第4步后

make -j4

7.sudo make install

搞定！
