opencv3.4.0+opencv_contrib3.4.0+cmake3.14.1+VS2015编译、配置、删除配置opencv
VS2015删除opencv配置
如果VS先前已经配置过opencv，
进入文件夹：C:\Users\randongmei\AppData\Local\Microsoft\MSBuild\v4.0，打开Microsoft.Cpp.x64.user或Microsoft.Cpp.Win32.user文件
删除opencv相关的配置即可。
1.下载并安装
opencv下载地址 :https://github.com/opencv/opencv/releases
下载Source code不要下载.exe，cmake编译时需要source code中cmakeList.txt，如果没有会报错。
opencv contrlib下载地址：https://github.com/opencv/opencv_contrib/releases
cmake官网下载，https://cmake.org/download/
下载msi文件，双击就可以安装，安装时注意选择添加路径到环境变量和创建桌面按钮。
VS2015
链接：https://pan.baidu.com/s/1ckwI05Sm7QSNujTFCLVeyQ
密码：lx7q
下载后解压，双击vs_community.exe安装，注意安装的时候自定义安装，只选择visual C++其他的都不选。
2.cmake编译opencv 3.4.0
解压下载的opencv源码opencv-3.4.0.zip和opencv附加包opencv_contrib-3.4.0.zip，将解压的文件包放在同一路径下，我这里放在D:\\盘。
设置编译路径
where is the source code：opencv源码opencv-3.4.0.zip解压包中CMakeList.txt所在路径
where is the build the binaries：opencv编译后放置的路径。
编译opencv3.4.0
点击【configure】按钮
编译opencv_contrib-3.4.0
编译完opencv3.4.0后中间出现许多列表，下拉列表，找到OPENCV_EXTRA_MODULES_PATH,选择opencv_contrib中modules所在路径D:\opencv_contrib-3.4.0\opencv_contrib-3.4.0\modules，然后再次点击【configure】按钮，操作与编译opencv3.4.0相同。
生成代码，点击【generate】按钮
3.生成库文件
where is the build the binaries中选择的路径中找到opencv.sln，双击该文件，点击【Build】检查是否能编译成功。
一般情况下都能编译成功，成功后，选择 CMakeTargets下的INSTALL右键选择仅用于项目->仅生成INSTALL即可，之后会在where is the build the binaries中选择的路径中找到一个install文件夹
4.在VS中配置opencv
配置opencv的环境变量
在计算机-环境变量-path中增加：where to build the binaries中设置的路径\install\x64\vc14\bin
针对如何自动生成动态库列表,写了一个小工具,有兴趣的可以参考:VS2010配置opencv2.4.10+查找小工具生成lib文件名列表
