I've just recompiled without problem ffmpeg with libwebp-0.6.0, here are my
options :

ASS=yes CELT=yes DC1394=yes FAAC=yes FDK_AAC=yes FLITE=yes FREI0R=yes GME=yes
GSM=yes IEC61883=yes ILBC=yes LADSPA=yes LAME=yes MODPLUG=yes OPENAL=yes
OPENCORE=yes OPENCV=yes OPENSSL=yes OPUS=yes QUVI=yes RTMP=yes SCHROEDINGER=yes
SNAPPY=yes SPEEX=yes TWOLAME=yes VIDSTAB=yes WEBP=yes X264=yes X265=yes XVID=yes
ZMQ=yes ZVBI=yes

It looks to me the problem might be whith tesseract, and not libwebp.
Maybe you should try recompiling/installing tesseract ?
