开着飞机上谷歌软件，用于下载依赖
1下载源码
https://github.com/opencv/opencv/releases/tag/3.4.9
https://github.com/opencv/opencv_contrib/releases/tag/3.4.9
下载
2 编译
设置路径和生成路径
点击configure
点击finish
等待结束
中间有一个警报，不是报错，忽略
3开始配置
3-1 添加cuda
3-2 添加扩展库 注意路径 /
3-3 添加sifit 角点库
3-4 添加world库 编译到一个里面
3-5 选择编译版本
3-6 是否编译python可用的版本（默认选了，但是可不用）
然后点击生成
请注意，开着某飞机上谷歌，而以保证这个过程中下载一些需要的文件，也可以根据后期报错记录，手动下载。
问题1 缺少没有下载好的库，需要手动下载
这些都是配置过程中没有自动下载下来的，需要手动去网址下载
从下载记录找哪些没被下载，手动下载好，放在对应位置
第一组

第一个报错 解决方案
https://*.com/questions/46584000/cmake-error-variables-are-set-to-notfound
1) 寻找符合以下条件的行：
find_cuda_helper_libs(nppi)
并将其替换为以下行：
find_cuda_helper_libs(nppial) find_cuda_helper_libs(nppicc) find_cuda_helper_libs(nppicom) find_cuda_helper_libs(nppidei) find_cuda_helper_libs(nppif) find_cuda_helper_libs(nppig) find_cuda_helper_libs(nppim) find_cuda_helper_libs(nppist) find_cuda_helper_libs(nppisu) find_cuda_helper_libs(nppitc)
我尝试了以下方法并且成功了：
FindCUDA.cmake在库中更改nppi为几个拆分的。这必须在 3 个地方完成。请记住，此更改只是为了使其与 CUDA 9.0 一起使用，我不会检查版本或任何内容，如果您打算将其提供给具有不同 CUDA 版本的不同人，则应该这样做。
1) 寻找符合以下条件的行：
find_cuda_helper_libs(nppi)
并将其替换为以下行：
find_cuda_helper_libs(nppial)
find_cuda_helper_libs(nppicc)
find_cuda_helper_libs(nppicom)
find_cuda_helper_libs(nppidei)
find_cuda_helper_libs(nppif)
find_cuda_helper_libs(nppig)
find_cuda_helper_libs(nppim)
find_cuda_helper_libs(nppist)
find_cuda_helper_libs(nppisu)
find_cuda_helper_libs(nppitc)
2）找到行
set(CUDA_npp_LIBRARY "${CUDA_nppc_LIBRARY};${CUDA_nppi_LIBRARY};${CUDA_npps_LIBRARY}")
并将其更改为
set(CUDA_npp_LIBRARY "${CUDA_nppc_LIBRARY};${CUDA_nppial_LIBRARY};${CUDA_nppicc_LIBRARY};${CUDA_nppicom_LIBRARY};${CUDA_nppidei_LIBRARY};${CUDA_nppif_LIBRARY};${CUDA_nppig_LIBRARY};${CUDA_nppim_LIBRARY};${CUDA_nppist_LIBRARY};${CUDA_nppisu_LIBRARY};${CUDA_nppitc_LIBRARY};${CUDA_npps_LIBRARY}")
3）找到未设置的变量并添加新变量所以，找到
unset(CUDA_nppi_LIBRARY CACHE)
并将其更改为：
unset(CUDA_nppial_LIBRARY CACHE) unset(CUDA_nppicc_LIBRARY CACHE) unset(CUDA_nppicom_LIBRARY CACHE) unset(CUDA_nppidei_LIBRARY CACHE) unset(CUDA_nppif_LIBRARY CACHE) unset(CUDA_nppig_LIBRARY CACHE) unset(CUDA_nppim_LIBRARY CACHE) unset(CUDA_nppist_LIBRARY CACHE) unset(CUDA_nppisu_LIBRARY CACHE) unset(CUDA_nppitc_LIBRARY CACHE)
此外，OpenCVDetectCUDA.cmake您还必须删除不再受支持的 2.0 架构。
它有：
...
set(__cuda_arch_ptx "")
if(CUDA_GENERATION STREQUAL "Fermi")
set(__cuda_arch_bin "2.0")
elseif(CUDA_GENERATION STREQUAL "Kepler")
set(__cuda_arch_bin "3.0 3.5 3.7")
...
它应该是：
基本上删除了第一个 if 并且第一个 elif 变成了一个 if。
...
set(__cuda_arch_ptx "")
if(CUDA_GENERATION STREQUAL "Kepler")
set(__cuda_arch_bin "3.0 3.5 3.7")
elseif(CUDA_GENERATION STREQUAL "Maxwell")
set(__cuda_arch_bin "5.0 5.2")
...
同时修改，去掉2.0
set(__cuda_arch_bin "2.0 3.0 3.5 3.7 5.0 5.2 6.0 6.1")
修改后
set(__cuda_arch_bin "3.0 3.5 3.7 5.0 5.2 6.0 6.1")
