WebP port to Unity WebGL

[Suntabu]

Hello,

My unity webgl game wanna use WebP as raw texture format, but I could not 

set-up the compile file properly, here is the file locat at "Asset/WebP/Plugins/WebGL/webp.cpp":

It produced many compile errors:

if you guys need this project to reproduce these problems, here is the repo

why not link against the precompiled libraries? Including all the source files into a single

one is really not recommended....

Yes, I've imagined using precompiled libraries by following this file instruction,

but it produced js and wasm files that could not be used by Unity.

So I don't know how to integrated webp lib into unity WebGL now

This is indeed the instructions for building the javascript/WASM version of the library, probably not what you need.

The instructions for building the library for C/C++ are available in the main README file here:

  https://chromium.googlesource.com/webm/libwebp/+/refs/heads/master/README

(linux instructions summary here: http://www.linuxfromscratch.org/blfs/view/svn/general/libwebp.html)

hello， I've got this work by put src files into plugins.

It just worked.

Thanks for your help
