title: in QtCreator, how to control the build progress bar with compilation progress
body: <p>I'm using <strong>QtCreator</strong> with a <strong>custom toolchain, <em>make.bat</em></strong>, under windows.
  This <em>make.bat</em> makes all the source syncqing and compiling stuff. <em>It</em> has many steps, and takes a while. </p>
  
  <p>However, since QtCreator doesn't know anything about what's my <em>make.bat</em> doing, the QtCreator building progress bar (the green one on the right bottom corner) doesn't grow little by little. It just changes from 0 to 100%, all of a sudden, when my <em>make.bat</em> is finished with errorlevel 0.</p>
  
  <p><strong>Is there a way a can tell QtCreator the progress of compilation?, so that QtCreator can update de green build progress indicator accordingly</strong></p>
  
  <p>for example, I could print some text in my <em>make.bat</em>, such as:</p>
  
  <pre><code>call do_Stuff_1.bat
  echo [ 25%%] syncqing...
  call do_Stuff_2.bat
  echo [ 50%%] parsing hola.cpp...
  call do_Stuff_3.bat
  echo [ 75%%] compiling...
  call do_Stuff_4.bat
  echo [100%%] done
  </code></pre>
  
  <p>And QtCreator could parse it (such as it parse the errors and warnings) and update the building progress indicator</p>
  
  <p>Maybe I can create a plugin?</p>
