在eclipse中找不到Opencv库文件

我正在尝试开发一个使用opencv的简单c++项目。我紧随其后http://docs.opencv.org/doc/tutorials/introduction/linux_eclipse/linux_eclipse.html网站但eclipse显示类似的错误

/usr/bin/ld: cannot find -llibopencv_photo
/usr/bin/ld: cannot find -llibopencv_stitching
/usr/bin/ld: cannot find -llibopencv_superres
/usr/bin/ld: cannot find -llibopencv_ts
/usr/bin/ld: cannot find -llibopencv_video
/usr/bin/ld: cannot find -llibopencv_videostab
/usr/bin/ld: cannot find -llibopencv_calib3d
/usr/bin/ld: cannot find -llibopencv_contrib
/usr/bin/ld: cannot find -llibopencv_ocl
/usr/bin/ld: cannot find -llibopencv_core
/usr/bin/ld: cannot find -llibopencv_core

/usr/bin/ld: cannot find -llibopencv_gpu
/usr/bin/ld: cannot find -llibopencv_highgui
/usr/bin/ld: cannot find -llibopencv_imgproc
/usr/bin/ld: cannot find -llibopencv_legacy
/usr/bin/ld: cannot find -llibopencv_ml
/usr/bin/ld: cannot find -llibopencv_nonfree
/usr/bin/ld: cannot find -llibopencv_objdetect
collect2: ld returned 1 exit status
make: *** [MyProject] Error 1`

我以以下方式包含了库及其路径。

项目->房地产

在C/C++构建->设置中。

In GCC C++ Compiler ->Includes. 
In Include paths(-l) I have added /usr/local/include/opencv.
In GCC C++ Linker 
I have added the path (-L) as /usr/local/lib and also library names.

谁能告诉我这个错误的原因吗？
