title: Install and use QWT under Mac OS X
body: <p>I am currently trying to get QWT 6.1.0 running under MAC OS X 10.7.5.
  I followed the instructions over here --> <a href="http://qwt.sourceforge.net/qwtinstall.html" rel="nofollow noreferrer">http://qwt.sourceforge.net/qwtinstall.html</a>
  I didn't changed something inside the configuration files. </p>
  
  <p>So everything worked fine, but now I want to use the qwt-libary inside my own Project.
  I added the following line to my .pro</p>
  
  <pre><code>INCLUDEPATH +=  /Users/userX/Downloads/qwt-6.1.0/src
  </code></pre>
  
  <p>So my Project is now able to find all the header Files.
  But I also have to link against the libary. But I dont know how to do so.
  I tried using something like this:</p>
  
  <pre><code>LIBS  += -L /usr/local/qwt-6.1.0/lib -lqwt
  </code></pre>
  
  <p>But than I get an error called "libary not found for -lqwt".</p>
  
  <p>What I am doing wrong? 
  How can I link against the library or how could I import the qwt framework into my project? </p>
