title: Cannot find my python3 config-dir in order to configure vim with python3 support
body: <p>My end goal is to have the YouCompleteMe Pluggin for Vim. As a prerequiste I need my Vim to be configured for python3.</p>
  
  <p>Previous when configuring with python I used the following command </p>
  
  <p><code>./configure --enable-pythoninterp=yes</code></p>
  
  <p>From searching it looks like the configure command for python3 is</p>
  
  <p><code>./configure --enable-python3interp=yes --with-python3-config-dir=????</code></p>
  
  <p>Unfortunately all the search results shows a pathway of <code>/usr/lib/python3...</code> No such path exists for me.</p>
  
  <p>I do have python 3, running <code>which python3</code> results in <code>/usr/bin/python3</code></p>
  
  <p>How can I find the route to my python3 config dir?</p>
