missing `libavutil.pc` build failure on windows

I am on windows and I installed the full shared Gyan 6.1.1 build but I can't seem to find any .pc files included.

I tried following the build guide from https://github.com/zmwangx/rust-ffmpeg/wiki/Notes-on-building and have installed and added LLVM and ffmpeg to path.

I had the same problem with ffmpeg-the-third and would love to have any help in trying to get one of the ffmpeg binding libraries to run on my machine. Apologies if the question is naive, I don't know much about this windows version:

OS Name:                   Microsoft Windows 11 Pro
OS Version:                10.0.22631 N/A Build 22631

mwe (reproducible for me on windows):

cargo new ffmpegtest
cd ffmpegtest
cargo add ffmpeg-next 
cargo build

  The system library `libavutil` required by crate `ffmpeg-sys-next` was not found.
  The file `libavutil.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
  The PKG_CONFIG_PATH environment variable is not set.

  HINT: if you have installed the library, try setting PKG_CONFIG_PATH to the directory containing `libavutil.pc`.

  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

thanks!
