OpenCV4.1.1 + contrib VS2017环境配置

contrib各个版本下载地址：https://github.com/opencv/opencv_contrib/releases 

Contrib主要是需要face相关的文件，属于一个扩展包吧，需要下载cmake编译

source选择OpenCV4.1.1中的sources

build选择一个新文件夹，为了生成编译后的文件

第一次点击Configure会让你选择VS版本，记得选择对应系统位数的！

Configure过程中第一次红色，再Configure一次，然后全变成白色，设置OPENCV_EXTRA_MODULES_PATH为下载的Contrib中的modules目录，需要下载同一版本的，再进行Configure，还会出现一次红色，再进行一次Configure，全部变成白色后，点击Generate

在你build中选择的文件夹会生成如下文件

用VS打开，然后生成解决方案，没有错误就说明生成成功了！

接下来选择INSTALL，右键->仅用于项目->仅生成INSTALL，等待结束！

回到自己的项目中，添加依赖项，跟开始设置OpenCV相同，系统环境变量和VS的环境

设置VS

包含目录和库目录如下
