Qt5 Project on Windows with MinGW

I have been using Visual Studio 2012 for a Qt/C++ project.

I am trying to migrate over to MinGW so that I can use C++11 entirely instead of the partial support that MSFT's compiler offers. Using CMake to generate the project and making was proceeding very well, compiling all the subprojects and the main project itself.

However, the linking is giving me some errors and I'm not sure how to resolve them:

The project compiles and links just fine using Visual Studio (and Xcode, FWIW), so I'm not sure what the linker is missing.

Can anyone offer any suggestions?

You need to download Qt for MinGW (or build it yourself, if you're using a different version of MinGW than the version the Qt release was built with.) The VS version of Qt cannot be used with MinGW.
