GStreamer 1.18 MSVC pkg-config

[Cameron Blomquist]

I'm working on Windows with gstreamer-rs and just updated to 1.18 from 
1.17.2. I switched my build configuration to use the new MSVC variable 
but I am still unable to build.

I have my environment set up as:

PATH = "${PATH};${GSTREAMER_1_0_ROOT_MSVC_X86_64}\\bin"
PKG_CONFIG_PATH = "${GSTREAMER_1_0_ROOT_MSVC_X86_64}\\lib\\pkgconfig"

I found that all the pkg-config files use the prefix 
"c:/projects/repos/cerbero.git/build/dist/msvc_x86_64" which does not 
exist. Is this intentional? I am not too familiar with pkg-config, so I 
do not know if I am doing something wrong or if this is a new issue. If 
it is an issue, I don't know which project this would be for.

Tried to compare the new pkgconfig with the old, but the new install 
seems to have nuked the old pkgconfig without removing anything else.
