title: How to enable ccache on Linux
body: <p>There is very little documentation on enabling <code>ccache</code> on GNU/Linux. Here is a response from <a href="http://launchpad.net" rel="noreferrer">launchpad.net</a>:</p>
  
  <blockquote>
    <p>At the moment, I think the best way to enable ccache is to add
    "/usr/lib/ccache" to the front of your path. If you want to enable it
    for all users by default, change the PATH variable in
    /etc/environment.</p>

  <p>Can someone give me more information on enabling <code>ccache</code>?</p>
