win7下qt+opencv的环境配置

博客http://blog.youkuaiyun.com/qiurisuixiang/article/details/8665278已经完整地介绍了整个环境配置。需要一步不差按原执行。需要说明的是，几个path的设定，千万不能有错，否者接下来的程序编译将会出错。path增加：

D:\Qt\Qt5.4.2\5.4\mingw491_32\bin;#你的qt安装目录

D:\opencv\bin;#你的opencv安装目录

D:\CMake\bin;#你的cmake目录

D:\Qt\Qt5.4.2\Tools\mingw491_32\bin #你的qt目录，是否和D:\Qt\Qt5.4.2\5.4\mingw491_32\bin重复？没关系，不影响你的程序便编译。

opencv的库设置，不同的版本做不同的选择，这里是opencv2.49：

INCLUDEPATH +=D:\opencv\include\opencv\

            D:\opencv\include\opencv2\

            D:\opencv\include

LIBS    +=\

        d:\opencv\lib\libopencv_calib3d249d.dll.a\

        d:\opencv\lib\libopencv_contrib249d.dll.a\

        d:\opencv\lib\libopencv_core249d.dll.a\

        d:\opencv\lib\libopencv_features2d249d.dll.a\

        d:\opencv\lib\libopencv_flann249d.dll.a\

        d:\opencv\lib\libopencv_gpu249d.dll.a\

        d:\opencv\lib\libopencv_highgui249d.dll.a\

        d:\opencv\lib\libopencv_imgproc249d.dll.a\

        d:\opencv\lib\libopencv_legacy249d.dll.a\

        d:\opencv\lib\libopencv_ml249d.dll.a\

        d:\opencv\lib\libopencv_objdetect249d.dll.a\

        d:\opencv\lib\libopencv_video249d.dll.a
