Trying to compile libwebp with CMAKE_OSX_ARCHITECTURES="x86_64;arm64" (also called as universal binary), will always fail due to SIMD intrinsics check. CMake passes `-arch x86_64 -arch arm64` into the compiler during `check_c_source_compiles`, which will always fail for any flag, because either x86_64 or arm64 won't have it. This also results in you not being able to compile the library due to errors like "SSE2 register return with SSE2 disabled". Change-Id: I32a41e4c64ce8c6a043083023a4018d512be124b

WebP codec is a library to encode and decode images in WebP format. This package contains the library that can be used in other programs to add WebP support, as well as the command line tools 'cwebp' and 'dwebp' to compress and decompress images respectively.
See https://developers.google.com/speed/webp for details on the image format.
