[vtkusers] Qt Example build errors

[Dean Inglis]

Im trying out Qt (Im a Qt newbie) with VTK under MinGW on Win32 Vista,
CMake 2.8, shared builds of Qt and VTK.  I ran into a
few snags while compiling code from the Wiki Examples/Cxx/Qt/RendewWindowUi.

1) SimpleViewUI.cxx refers to a missing header: ui_SimpleView.h

here is the error output from mingw32-make:

D:\Developer\Releases\MinGW\SHARED\vtkQt\Qt2>mingw32-make

2) I tried opening up SimpleViewUI.ui in Qt Designer and while loading I get 
a popup error message:
  The specified qrc file
  D:/Developer/Sources/Auxiliary/QtExamples/Qt2/Icons/icons.qrc
  could not be found.  Do you want to update the file location?
