十分好的一篇文章，讲的很清楚。
OpenCV_contrib编译安装
这里需要注意第一次configure后（全白），也要点击generate，再次configure和generate。
VS打开记得要用管理员权限下,进行编译
报错类型一般如上所述，原因是因为VS没有以管理员身份运行，在路径C:\Program Files (x86)\Common Files\Microsoft Shared\MSEnv下找到VSLauncher.exe，右键→属性→兼容性→勾选以管理员身份运行；
cmake编译时无法打开 python36_d.lib 的问题
在对应的 pyconfig.h 文件中做出如下修改：
都改成
并且要将 define Py_DEBUG(337 句）注销：
成功
配置
首先配置环境变量，不说了，比较简单
然后在工程里配置如下：
添加如下：
