OpenCV入门（0）——安装，配置

     1.  下载Opencv，安装

      2.  配置环境变量

               一、系统变量 Path：添加D:\opencv\opencv-2.4.9\opencv\build\x86\vc12\bin

               二、用户变量：添加opencv变量，值D:\opencv\opencv-2.4.9\opencv\build\x86\vc12\bin变量值实际为bin文件夹的路径；

               说明：无论你系统是32位仍是64位，路径目录均选择X86，由于编译都是使用32位编译；若是选用X64，则程序运行时候会出错。

               重启！

       3.  VS工程设置：

           1, 在项目->属性对话框中，左侧“配置”选择“Debug”，而后“配置属性”->VC++目录，在右侧设置“包含目录”，新添加：

                D:\opencv\opencv-2.4.9\opencv\build\include

                D:\opencv\opencv-2.4.9\opencv\build\include\opencv

                D:\opencv\opencv-2.4.9\opencv\build\include\opencv2

           2, 在“库目录”，添加:

                D:\opencv\opencv-2.4.9\opencv\build\x86\vc12\lib

           3,【通用属性】 ->【连接器】->【输入】->【附加的依赖项】

                debug:
