GraphicsMagick & Qt -- undefined reference to '_imp__InitializeMagick' (MinGW Win XP)

[faraday]

Trying to get GraphicsMagick to play with Qt. Built GraphicsMagick from source using the same MinGW that came with Qt5.3. GM was built to yield static libraries. MSYS GUI wasn't installed so used MSYS command line shell and as a result had to put GM source inside the MSYS file tree, hence the weird locations shown in the .pro file.

Getting this error: undefined reference to '_imp__InitializeMagick'.

I may be mixing things up somehow between the 'C' API and C++. With C++ I'm getting about the same error but it's mangled. I'd prefer to go the 'C' route as I know it better. I apologize if this isn't an appropriate question for this forum but I don't know where else to go with it. Thanks

Here is the .pro file:
