How do I build a debug mode QT app that links to a lib built in release mode?

[Joachie]

Try using Qt debug libraries built against the non-debug msvcrt. You won't be able to debug into the crt code, obviously, but it should let you debug into the Qt libraries at least.

Does that mean I have to rebuild QT so that it links against the non-debug MSVCRT? If so, how do I instruct the configure.exe so that it does this?
