I suppose this is related to:

commit dd1081763c914914aedc36bc6d46a3a158e24777
Author: Pascal Massimino <pascal.massimino at gmail.com>
Date:   Wed Jul 18 21:58:53 2012 +0000

    rename 'use_argb_input' to 'use_argb'
    
    long name, and there's not really an 'output' equivalent
    
    Change-Id: I9133ff734ae8d6572cb2f607211361f011fc0bc1

So...

[~/src/libwebp]☭ git checkout dd1081763c914914aedc36bc6d46a3a158e2477
[~/src/libwebp]☭ git describe
v0.1.3-606-gdd10817
[~/src/libwebp]☭ git tag
v0.1.2
v0.1.3
v0.1.99
v0.2.0
v0.2.0-rc1
v0.2.1
v0.3.0
v0.3.0-rc6
v0.3.0-rc7
v0.3.1
v0.3.1-rc1
v0.3.1-rc2
v0.4.0
v0.4.0-rc1
v0.4.1
v0.4.1-rc1

I suppose the next version is v0.1.99 but it sounds like a beta or something.
So I'd just pick 0.2.0.

Which basically translates to:

enabled libwebp           && require_pkg_config "libwebp >= 0.2.0" webp/encode.h WebPGetEncoderVersion
