C++ /usr/bin/ld:找不到-lopencv

我试着按照这个安装opencv ubuntu 14.04。在执行这个之后，我在QT中创建了一个C++项目。将显示一条错误消息：

    g++ -m64 -o test main.o mainwindow.o moc_mainwindow.o  
     -L/usr/X11R6/lib64 -L/usr/local/lib -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib 
    -lopencv_legacy -lopencv_flann 
    -lopencv_xfeatures2d -lopencv_imgcodecs -lQt5Widgets -L/usr/lib/x86_64-linux-gnu -lQt5Gui -lQt5Core -lGL -lpthread 


//error is here

好的，安装所需的库。我安装时使用了哪些库？谢谢您在本例中缺少额外模块-请参阅此处@y300，谢谢您的帖子，我解决了另外两个软件包，但此软件包“/usr/bin/ld:not find-lopencv_xfeatures2d”尚未安装或添加。感谢您的帮助：）有人能帮我确保安装此xfeatures2d开发库吗？谢谢，请安装所需的库。我在安装时使用了哪些库？谢谢您在本例中缺少额外模块-请参阅此处@y300，谢谢您的帖子，我解决了另外两个软件包，但此软件包“/usr/bin/ld:not find-lopencv_xfeatures2d”尚未安装或添加。感谢您的帮助：）有人能帮我确保安装此xfeatures2d开发库吗？谢谢
