prevter e329ca4c26 Fix universal macOS binaries builds
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".

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.
