title: Adding resources to QML project results in very slow compilation
body: <p>I have added some icons to the resource file of my project and suddenly every tiny change to the QML code results in 7-8 seconds of wait time before the project is ran, it almost feels like it is recompiling the C++ code, but in reality that's the delay from the "compilation" of the qrc file.</p>
  
  <p>I tried disabling qrc compression in hopes that it will get faster, but it didn't have any effect. This is very strange and annoying, considering the fact I am using a high end system with a fast CPU and SSD - the extra resources are only 2 megabytes, why is it taking so long? Adding the same files to an archive with high compression takes about 5 milliseconds.</p>
