Development of GStreamer on Windows?

[Thibault Saunier]

Hello Scott,

Thanks for figuring all that out! I gave your instructions a try but I
think you are missing a step to get the pkg-file point to a place that
msvc understand for the -I as they point to /mingw64/include/XXX but
that does not work, can you remember what you do? What am I missing?
:)

I am also coming up with a simple script to do that all in one step.

Thanks

Thibault
