Using GraphicsMagick's ./configure with MXE

[dan9er]

I've installed MXE on my Linux laptop to cross-compile my project to Windows. One of the libraries I'm using is GraphicsMagick, which is available in MXE's Makefile rules.

My problem is that there doesn't seem to be a way to access GM's ./configure in order to disable or enable it's features to compile. I only want to statically link a minimal version of GM in order to keep my executable size low.

Is there a way access GM's ./configure before it's compiled for MXE?
