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

第一个报错 解决方案

https://stackoverflow.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")
