Imo, it is a very bad idea to copy somebody else's extra-version name for your
binaries.

What does the following show?
$ pkg-config --libs libwebp
If you don't have pkg-config, you can use the configure option
--pkg-config=true but
you will have to provide the library yourself (--extra-libs=-lwebp or similar).
