title: How to link to shared lib from shared lib with relative path?
body: <p>I'm working on a Firefox plugin that uses external libraries to render 3D graphics on the browser.</p>
  
  <p>The problem is that I want the plugin to use external libraries packed with it without changing the <code>LD_LIBRARY_PATH</code> variable.<br>
  The libraries are installed in a position relative to the plugin (a shared library too), while the actual executable (i.e. the browser) can be located somewhere entirely else.</p>
  
  <p>I'm testing it on Ubuntu (no problem at Windows version of the plugin)
  My dependencies are OpenSceneGraph libraries and static compilation will make the plugin really big (not an option if there is another one).</p>
