关于Qt配置OpenCV后构建不了的问题

配置完opencv后，想着试一下show一张图片

结果：
undefined reference to “imread(…)”
undefined reference to “imimshow(…)”
undefined reference to “waitKey(…)”
…

可是我已经在.pro文件里面添加了INCLUDEPATH += …和LIBS += …

我想一定是这里面出了问题，要么是路径有问题，要们是有些库没添加进去（lib是我手动添加的），看网上说，这种问题一般是opencv_imgcodecs库没写进去，可是我查看了一下，在里面呢。

最后，我在网上找问题的时候无意中看到了一篇文章

INCLUDEPATH +=  D:/opencv3.2_mingw5.3.0/include\
                D:/opencv3.2_mingw5.3.0/include/opencv\
                D:/opencv3.2_mingw5.3.0/include/opencv2
 
LIBS += D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_core320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_highgui320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_ml320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_imgproc320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_imgcodecs320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_stitching320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_calib3d320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_features2d320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_flann320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_video320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_objdetect320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_videoio320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_photo320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_shape320.dll.a\
        D:/opencv3.2_mingw5.3.0/x86/mingw/lib/libopencv_superres320.dll.a\

我才猛然意识到问题出在哪儿，请看：

然后另一种写法是老老实实在每一行都加上"INCLUDEPATH +=”、“LIBS +=”

最后，整整花了3天时间在Qt配置OpenCV，终于show出了图片
