title: update .bashrc file to locate opencv libraries
body: <p>I am not a sudo user in a server and want to use my version of opencv.
  There is .bashrc file for each user. I too have it. Please tell how to set path of local installation of opencv into .bashrc.
  Each time I set path in .bashrc and do source ~/.bashrc. And check the version, its still the same. </p>
