New pkg-config requirement to find libogg and libopus does not play well with Win32

[silverbacknet]

It used to be that I could use cmake to generate VC project files, manually specifying the location of headers and libs if necessary. Sometime recently, a new dependency on pkg-config was inserted in an effort to simplify the logic, which may work well for *nix, but seems to completely fail in a win32 environment. First configuration fails on a missing pkg-config, which is not a standard part of any win32 build-chain, and even once acquired, it's useless because builds simply aren't packaged that way in win32, despite using bog-standard cmake for libogg and libopus, which built just fine.

Now, short of butchering the cmake files, I have legitimately no idea how to add the library information or bypass a check that can never work on this system. Manually setting the location simply results in it being reset when pkg-config fails. I tried setting up vcpkg but that doesn't seem to work either.

I thought cmake had its own package description format, and the ogg and opus library locators were supposed to use that, and only fall back the pkg-config?
