title: How can i use a private installation of wxWidgets
body: <p>I have two installations of <code>wxWidgets</code>, one in <code>/usr/...</code> and one private.
  I don't have permissions to change the central directory.
  My question is how can i make my <code>private</code> installation the <code>active</code> one?</p>
  
  <p>If i only add it to the PATH setenv, it dosn't work correctly since i'm missing the LIBS.</p>
