Gosh man…..


configure:13013: checking for libwebp >= 0.6.0
configure:13020: $PKG_CONFIG --exists --print-errors "$WEBP_MODULE"
configure:13023: $? = 0
configure:13037: $PKG_CONFIG --exists --print-errors "$WEBP_MODULE"

pkg_cv_WEBP_CFLAGS=-I/opt/homebrew/Cellar/webp/1.2.1_1/include
pkg_cv_WEBP_LIBS='-L/opt/homebrew/Cellar/webp/1.2.1_1/lib -lwebp'

I also have a “decode.h” at /opt/homebrew/Cellar/webp/1.2.1_1/include/webp/decode.h, in "image.c"
here is an include "webp/decode.h”, so in my theory it should work, but it does not.

As I use to say:  "IT is not handicraft, it’s art, you never know what it ends up with"
