错误necessitas同时使用OpenCV的库

我在QT的Android设备编程，需要使用OpenCV进行捕捉从相机。我已经使用Qt的创造者和链接的OpenCV和使用的相机，但Qt中为Android（necessitas）时生成程序，显示此错误：错误necessitas同时使用OpenCV的库

我首先下载最新版本的OpenCV和构建它，然后使用库。也

project.pro

添加此行：

INCLUDEPATH += "C:\OpenCV2.3.1\include\opencv" 
LIBS +="C:/OpenCV2.3.1/libs/armeabi-v7a/libopencv_androidcamera.a" \ 
"C:/OpenCV2.3.1/libs/armeabi-v7a/libopencv_calib3d.a" \ 
"C:/OpenCV2.3.1/libs/armeabi-v7a/libopencv_calib3d_pch_dephelp.a" \ . 
...

可以necessitas支持OpenCV的？为什么显示这个错误？

对不起我的英语。

查找和添加libtiff.a，它可能会在OpenCV的第三方库目录。

原来的.a文件的为了重要。把它们按上述顺序（将路径更改为你的路）为我工作：
