[Edward Shi]

Hi, FFMPEG professor:


I tried to enable webp for ffmpeg, and got below error:


configure:

./configure --cc=/usr/bin/clang --prefix=/opt/ffmpeg --extra-version=tessus --enable-avisynth --enable-fontconfig --enable-gpl --enable-libass --enable-libbluray --enable-libfreetype --enable-libgsm --enable-libmodplug --enable-libmp3lame  --enable-libopus --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libvidstab  --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libx264 --enable-libx265 --enable-libxvid --enable-libzmq --enable-version3 --disable-ffplay --disable-indev=qtkit --enable-libopenjpeg  --enable-libopenh264  --enable-libkvazaar --enable-libilbc  --enable-libfdk-aac --enable-nonfree --enable-encoder=aac --enable-libwebp


ERROR: libwebp not found using pkg-config

    both under

       /usr/local/lib

   and

    /usr/local/Cellar/webp/0.6.0_2/lib/
