Re: UPDATE: libwebp - CMake

it'll be due to dropping the static library, iirc something is messed up with detecting shared libs in python and it doesn't work correctly unless there's either a .a or .so symlink

Here is a conversion of libwebp back to using CMake again.

I was wondering why OpenImageIO's WebP support wasn't being

built and its because of the missing CMake module in libwebp.

But as stated with the previous attempt something breaks in

py-Pillow. When I added webp=enable it complained about not

being able to find the library.

Could someone who understands Python / py-Pillow try to take

a look into what is going on?
