title: Running debug mode in Qt Creator
body: <p>I am trying to compile some demo code (specifically, the pcl_visualizer demo that comes with the Point Cloud library). When running debug by clicking the green arrow with the magnifying class, I get the following errors:</p>
  
  <pre><code>This does not seem to be a "Debug" build.
  Setting breakpoints by file name and line number may fail.
  
  Section .debug_info: Not found.
  Section .debug_abbrev: Not found.
  Section .debug_line: Not found.
  Section .debug_str: Not found.
  Section .debug_loc: Not found.
  Section .debug_range: Not found.
  Section .gdb_index: Not found.
  Section .note.gnu.build-id: Found.
  Section .gnu.hash: Found.
  Section .gnu_debuglink: Not found.
  </code></pre>
  
  <p>Furthermore, none of the breakpoints I have inserted are breaking the program, and they all have little hourglasses hovering over.</p>
  
  <p>In <code>Projects</code>, the <code>Debug</code> mode is selected in <code>Build Settings</code>.</p>
  
  <p>Why does my code not seem to be debugging correctly?</p>
