VP9お試しビルド
うまく行かなかったので下記の方法にて解決
VP9お試しビルド（その２） - fftester06’s blog

まあでもこれでビルドが最後まで通るようになった！
生成されたlibvpx.aをMinGWに持ってきて、simple_encoderをコンパイルしてみる。

cygwinでは不要だったsetjmp.hがMinGWでは必要な模様
→vp8_dx_iface.cに追加
同様にunistd.hが必要
→systemdependent.cに追加
...ここまでくるとMinGW用にbashとmakeがほしいような・・・。
しかもビルドがうまく行かないので、Git bash上に環境構築してみることに。
