title: Build Qt Project in Debug Mode from Command line (aka bash script) in Linux
body: <p>I already have a project with a .pro file that can be built in debug and release mode. So my question is what is the options on the commandline that I have to specify if I want to build my binaries with debug information. Here is an example building in release using a bash script:</p>
  
  <pre><code>cd ${CHECKOUT_DIR_DEV_OGL_DX_ENGINE_SKIA};
  echo `date`: "Running \`qmake\` on Skia";
  qmake&amp;&gt;${SKIA_LOG};
  buildstatus $? "Running \`qmake\` on Skia";
  echo `date`: "Running \`make\` on Skia";
  make&amp;&gt;${SKIA_LOG};
  buildstatus $? "Running \`make\` on Skia Please see ${SKIA_LOG}";
  </code></pre>
  
  <p>What do I need to add to get it now to also build in debug mode?</p>
