I have problem getting qwt working on Windows using MVC 10 compilers.

This is the error I'm getting:
The plugin 'C:/Qt/Qt5.0.1/Tools/QtCreator/bin/designer/qwt_designer_plugin.dll' uses incompatible Qt library. (Cannot mix debug and release libraries.)

I recorded video of my actions to easily demonstrate the way I'm doing it.
Watch it in HD so you can see better.
