This is the check for vp9 in ffmpeg's configure script:

    enabled libvpx_vp9_encoder && {
        use_pkg_config libvpx_vp9_encoder "vpx >= 1.3.0" "vpx/vpx_encoder.h vpx/vp8cx.h" vpx_codec_vp9_cx ||
            check_lib libvpx_vp9_encoder "vpx/vpx_encoder.h vpx/vp8cx.h" "vpx_codec_vp9_cx VP9E_SET_AQ_MODE" -lvpx
    }

We would need to see your config.log to see what fails. As that file is
very large, could you check for lines which look relevant? Check for
the occurance of "libvpx_vp9_encoder" and look at the lines after. They
will tell us how the check is failing.

(I'm too lazy to build latest libvpx, and couldn't find an obvious
change in their repo.)
