anna在实验室配置OpenCV的时候，按照中文网站的介绍，很顺利的就完成了。可是回到家情况就大不一样！！总是在链接的时候报错，不是少这个lib就是少那个lib大哭最后查明是anna马虎，忘了将C:\Program Files\OpenCV\lib加入Library files！下面是详细的配置过程：
1.安装OpenCV
2.检查C:\Program Files\OpenCV\bin是否已经被加入到环境变量PATH，如果没有，请加入。加入后需要注销当前Windows用户（或重启）后重新登陆才生效。
3.配置VC
全局设置：
菜单Tools->Options->Directories：先设置lib路径，选择Library files，在下方填入路径：
C:\Program Files\OpenCV\lib 《《------这一行字比较不醒目，但是很重要滴！！不要忘记哦
然后选择include files，在下方填入路径：C:\Program Files\OpenCV\cxcore\include
C:\Program Files\OpenCV\cv\includeC:\Program Files\OpenCV\cvaux\includeC:\Program Files\OpenCV\ml\includeC:\Program Files\OpenCV\otherlibs\highguiC:\Program Files\OpenCV\otherlibs\cvcam\include然后选择source files，在下方填入路径：C:\Program Files\OpenCV\cv\src
C:\Program Files\OpenCV\cxcore\srcC:\Program Files\OpenCV\cvaux\srcC:\Program Files\OpenCV\otherlibs\highguiC:\Program Files\OpenCV\otherlibs\cvcam\src\windows最后点击“ok”，完成设置。项目设置：
每创建一个将要使用OpenCV的VC Project，都需要给它指定需要的lib。菜单：Project->Settings，然后将Setting for选为All Configurations，然后选择右边的link标签，在Object/library modules附加上
cxcore.lib cv.lib ml.lib cvaux.lib highgui.lib cvcam.lib
点击OK，就大功告成啦
