Compile Qtcreator with mingw ?

[tonnot]

I have search 'INSTALL_ROOT' at google. At the moment I dont know if this variable is used by QT or Mingw.
At QT Help the only link I can to find is : Installing Qt on Embedded Linux
So, I think that I can set the variable for this work (compile Qt Creator) and forget it , isn't ?

If they feel more comfortable with msvc then why shouldn't they be using it? What's the difference which compiler they use?

Because if I'm going to develop a custom widget with plugin aproach, If I have QT Creator (MSVC) , and build my plugin using mingw... (I have not MSVC of course).
I think the most of people uses one 'system' : all based in MSVC or Mingw, isn't ? So it would be interesting that QT offer a mingw or msvc based bin distribution ...
