title: Find OpenCV Version Installed on Ubuntu
body: <p>I would like to find out what version of OpenCV is installed on my computer (i am running Ubuntu 10.04). Is there a simple way to check it if ? If not then can i find out the directories where files (samples, etc) are installed ? </p>
  
  <p>I am trying to run some code that i have already tested on another computer with OpenCV 2.3 installed and i get many errors.</p>
