title: preprocessor definition / add a new profile
body: <p>I have two profile in my project, (debug and release) I want to add a new profile (debug2) and use sth like this:</p>
  
  <pre><code>#if defined(DEBUG)
      // func1();
  #elif defined(RELEASE)
      // func2();
  #elif defined(DEBUG2)
      // func3();
  #endif
  </code></pre>
  
  <p>but the problem is when I add a new profile and I try to build the program as debug2 <code>func3();</code> is disable</p>
  
  <p>Is there sth that I should do in <code>c/c++ -&gt; preprocessor -&gt; preprocessor definition</code>  ?</p>
