title: SonarQube not ignoring C++ code with // NOSONAR
body: <p>We're using <code>SonarQube 5.3</code>. One of the developers told that SonarQube is <em>not</em> ignoring a false positive although he marked it with <code>// NOSONAR</code> in source code.</p>

  <p>In Java it's working fine. Is there another way for C++? We're using <code>cppcheck</code> plugin.</p>
  
  <p>PS: I know the way marking it as false positive via UI. But it would be good to mark it right in the source code.</p>
