We're currently using faiss on arm64 on Windows, but we can't use the main branch as-is for that.

Have you tried to compile it by hand?

[davidmatson]

Yes, I think so. We currently get it compiling by patching in edits from this branch: https://github.com/es0m/faiss/tree/user/es0m/support-win-arm-builds (if that's what you mean by "by hand"; I may have misunderstood)

[mdouze]

Yes sure. So IIUC the only change in the C++ part is in platform_macros.h I think we are not going to include it the CircleCI contiuous intergation but we can accept this patch so that people can compile for arm64 windows themselves.

@mdouze - that would be great, thanks!

Yeah, I think the CircleCI part is a separate question. We consume via vcpkg, so if we could get whatever of the C++ & CMake parts needed so that it will "just work" for vcpkg consumers on Windows, that would be great.

@algoriddle what do you think about the cmake patch ?
