title: Boost with Qt Creator and Linux
body: <p>So I added:    </p>
  
  <pre><code>LIBS += 
         -lboost_system\                                                         
         -lboost_gregorian
  </code></pre>
  
  <p>To my projects .pro, but in Creator it says "cannot find -lboost_system".  I tried using "UNCLUDEPATH" but that broke the path for all libraries.</p>
  
  <p>Anyone have any ideas how to use boost::gregorian with Qt Creator?</p>
  
  <p>EDIT:  Below works to get it recognized, but breaks all other libraries.</p>
  
  <p>INCLUDEPATH +=     /usr/include<br>
  LIBS += -L"/usr/include/boost" -lboost_system -lboost_gregorian</p>
