Can anyone help with this problem?

Thx for reporting. This is the upstrean issue: https://github.com/microsoft/vcpkg/issues/33603

It seems the NEON files are not part of the compilation right? The GitHub issue does not have the full logs.

Also, it seems there is a package for 1.3.0 so was it compiling then?  According to https://vcpkg.io/en/packages.html

Thanks for the report. How is the library being configured and built? We have a nightly cmake based build for arm64 that passes using something like `cmake.exe -G "Visual Studio 17 2022" -A Arm64`. This looks like the required "*_neon" object files weren't included.

Thanks for the response, I was hoping to isolate this to a libwebp issue or an issue with vcpkg itself, which we don't maintain.

You can also try filing a bug at https://github.com/Microsoft/vcpkg so the maintainers can have a look at the issue.
