1、既然是开发环境，那么首先得下载安装包，这里注意以下版本问题：
opencv2.4.9
2、安装opencv2.4.9 ，首先解压opencv，记住解压路径，我以E:\Program Files为例子，
这里需要注意，软件要安装在Program Files (x86) 路径下面。
3、安装完成后要配置环境变量到path中；主要配置以下几个变量：
1.用户变量：添加opencv变量，值e:\Program Files\opencv\build
2.系统变量 Path：添加e:\Program Files\opencv\build\x86\vc12\bin
4、 VC++工程配置，这里需要在环境变量配置完毕后进行。注意重启IDE。
新建一个项目（这个应该都会吧）
选择.cpp.win32.user文件，双击打开视图->属性管理器
5、先选择VC++目录
将可执行文件目录
点击右边，选择编辑。配置工程包含目录（include）环境
6、最后一步附加依赖项的配置，输入下面的链接库名：
opencv_calib3d249d.lib
opencv_contrib249d.lib
opencv_core249d.lib
opencv_features2d249d.lib
opencv_flann249d.lib
