No headers or import library

I just installed the GraphicsMagick 1.3.7 Windows Q8 DLL package (after 
getting everything up and running on Linux, of course). The bottom of the 
text content on the last screen of the installer told me that I would find 
C++ headers and import libraries in appropriately named directories under my 
installation root, but they weren't there.

Is this correct? Did I do something wrong? Is it recommended that I just build 
the library from source for this application?

Thanks!

Nick
