[vpdq] Add support for Windows in vpdq pypy package

[therreher]

Does this software work with windows 10. I have ffmpeg and cmake installed but when I try to install I get this error:

Hmm, @ianwal had done a series of diffs to add windows support, but I don't think we built a new version at the end, which you've tried to pip install. Let me release a new version and see if that fixes it.

I have a windows machine, so should be able to test it.

The Python bindings I didn't have time to get working fully with Windows. It's a build issue. But, vpdq itself does build and work with Windows.

The way the binding builds with Cython is it passes the libav libraries as the environment variable LIBRARY_DIRS from CMake to Cython. When I tried to build with Windows it seemed like that was missing. It's probably a simple fix.

Here are some of my notes to get vpdq itself to build on Windows with MinGW #1331 (comment)

One way this could be done is if the platform is detected as Windows in the build script vpdq/vpdq-release.py, then have the user supply the location of the libav library dirs installed with MinGW. This wouldn't be pretty but it would work.

Finally repo'd on my side after remembering the correct sequence of installs to get visual studios to build opencv.

@therreher - any concerns with me converting this to a help request to add windows support for the cpp bindings?

That's find but I have another question. I saw in @ianwal notes"Install MinGW toolchain." Does FFmpeg need to be installed through MinGW because I installed it from https://www.gyan.dev/ffmpeg/builds/ and added the path manually.

Not sure. I don't have a lot of experience with MinGW. If it builds it builds. I would prefer to install through a package manager though.
