VS2017配置opencv-cmake源码-contrib
下载VS2017
下载CMake
官网-https://cmake.org/
下载
选择对应版本
选择自动配置系统路径
下载opencv
官网https://opencv.org/，进入github
下载opencv和contrib
CMake配置opencv及其contrib
1为下载完成的openev的路径
2为生成的，自定义一个mybuild文件夹
configure,选择X64
再点configure,可能会出现问题，第一次fonfigure会出现红，
下面是可能出现的问题
解决上述问题
ffmpeg_version.cmake有问题，从第二个路径下D:/…/CMakeDownloadLog.txt；
利用查找找到ffmpeg_version.cmake，然后从后面的网址下载，替换，其实可以利用D:\opencv4.1.0\opencv-4.1.0.cache中的ffmpeg和ippicv来复制粘贴（貌似是）
（据说不解决，一致configure到不红也可以）
勾选必要的选项
找到EXTRA_MODULES_PATH，添加contrib/modules（一定要定位到modules）
勾选ENABLE_NONFREE
configure，直到1不红了
generate
完成
最终mybulid里表面有一个opencv.sln
完成编译
用VS2017打开opencv.sln，（据说2019不行）
右键解决方案，然后生成解决方案，等待ing。完成
INSTALL，用于项目，仅生成，等待ing,完成
Release版本再做一遍
mybuild中出现了install,（此时可以删除mybuild中除了install中的其他文件）
VS配置opencv
新建空项目，先不建立源文件，然后属性管理器
注意：VS一般配置opencv会使Debug和Release版本不能同时运行，原因在于链接器的问题。下面的步骤可以解决
先右键添加属性表
新建opencv-debug
右键属性，打开属性管理器，VC++目录，包含目录，照样子导入两个文件
库目录，照样子导入lib
包含目录和库目录导入的都是mybuild中install的文件
链接器，输入，附加依赖项
对于debug模式，只，导入末尾带d的库，如下
具体库有多少，看install，X64，V15中有多少个带d的文件（不一定与下面的一样）
opencv_aruco410d.lib
opencv_bgsegm410d.lib
opencv_bioinspired410d.lib
opencv_calib3d410d.lib

opencv_ximgproc410d.lib
opencv_xobjdetect410d.lib
opencv_xphoto410d.lib
完成，点保存，不点保存会丢失
得到这样的文件
下次新建项目，先添加已有属性表，就可以，然后在建立源文件
Release版本也一样，新建属性表opencv-realeas
只有在附加依赖库不一样，导入如下不带d的库，保存
用的时候再添加现有属性表

BOOM！GOT IT！
