This looks fishy.

Is opus_multistream.h actually located in
/d/smallgame/ffmpeg_win/deps.posix/include/opus?

Could you try setting the environment variable PKG_CONFIG_SYSROOT_DIR
to "/d/smallgame/ffmpeg_win/deps.posix" before running configure? (I
don't know if configure should take over this, or if there's a proper
option. Since it's not a cross-compile, "--sysroot=" seems incorrect.)
