Rust gstreamer-full / static build

[Mattias Nordstrom]

The application is written in Rust and using the gstreamer, gstreamer-base
and gstreamer-app crates. Building and running against the installed
GStreamer (and devel) .msi works as expected. I'm using the
d3d11screencapturesrc, mfg264enc and appsink elements in my pipeline. I've
tried to build GStreamer from source "meson --default-library=static ...."
and it builds and creates a gstreamer-full-1.0.lib which I assume I should
be able to use for the static linking into my app. The Rust crates however
still seem to be trying to link against e.g. gobject-2.0 etc. and not
gstreamer-full-1.0. I've changed the PKG_CONFIG_PATH env variable to my
custom build pkgconfig path and it seems to be using that but still trying
to link against the individual libraries that the static full build doesn't
even produce.

I also tried to statically link against the official .msi install using the
env variable SYSTEM_DEPS_LINK = "static" but that didn't seem to do
anything.
