Creator Dependencies on Linux are not obvious enough.

When installing the Qt SDK, one must install several packages for it to work. On our wiki, we have documented what is needed:

"sudo apt-get install libglib2.0-dev libSM-dev libxrender-dev libfontconfig1-dev libxext-dev

If you're using QtOpenGL, you will also need:

sudo apt-get install libglui-dev"

This doesn't seem to be obvious enough though. This may be because people expect out of the box expirience. Ideally, we should call the distros installer to install these packages. If this is not possible, we should include this information (or a link to the docs) directly in the installer.

Note that the information on packages should be a bit more abstract, to allow users of other platforms an idea what they need to install.

I am making this a blocker because of the high feedback for this.
