[cairo] Build cairo with mingw for qt support

[Theuns Heydenrych]

Thanks for the reply.

I went through the whole procedure to build Qt5.3.2 with mingw, so i do
have all qt libraries in mingw available. I also supplied a QtGui.pc
package for the cairo configure script to pickup all the Qt relevant
information for the build. But it looks like the boiler plate source for
the qt drawing surface, is not for windows using mingw?

Below is the final result of the ./configure --enable-qt=yes script.
Xlib is not used, because it states "requires X development libraries", and
i do agree with that, because it is not present in the build environment.
So it looks like the Qt drawing surface can not be used with cairo in a
mingw build, because the cairo-boilerplate-qt.cpp includes X11/Xlib.h.
I am fine with it, if someone just can confirm that is the case, that the
qt drawing surface can not be configured for cairo using mingw?
I wanted to experiment with it anyhow, so its not a train smash, and i do
understand that the qt drawing surface is experimental at the moment, as it
states in the result of the configure script, but i just want to make sure,
that i do not miss anything.

Regards.
