    Revert "Fix configuration of webp libraries"
    
    This reverts commit de4277af009115ceba7fe920163c05c608ea9524.
    It breaks WebP support at least on my system.
    There's no reason to require libwebpdecoder library to be
    installed, since we don't use the functions from it, at least
    not in libwebp 1.2.1.
