title: /usr/bin/ld: cannot find -lopencv_contrib
body: <p>I am new to openCV 3.0. I installed Eclipse cdt, followed the instructions given <a href="http://docs.opencv.org/doc/tutorials/introduction/linux_eclipse/linux_eclipse.html" rel="nofollow">here</a>. Now when I build the project I get the following result:</p>
  
  <pre><code>18:15:16 **** Incremental Build of configuration Debug for project DisplayImage ****
  make all
  Building target: DisplayImage
  Invoking: GCC C++ Linker
  g++ -L/usr/local/lib -o "DisplayImage"  ./src/DisplayImage.o   -lopencv_core -lopencv_contrib -lopencv_legacy -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d  -lopencv_calib3d -lopencv_objdetect -lopencv_flann
  /usr/bin/ld: cannot find -lopencv_contrib
  /usr/bin/ld: cannot find -lopencv_legacy
  collect2: error: ld returned 1 exit status
  make: *** [DisplayImage] Error 1
  </code></pre>
  
  <p>I searched the /usr/local/lib where other libraries are present and I cant find these two files. What should I do now to solve this problem?</p>
