Additional context
ARM64 version compiles just fine:
vcpkg install abseil --triplet arm64-osx

The x64-osx version is required in the M1 because gRPC defines "host": true.

[autoantwort]

Maybe do #17344 as a workaround

[JackBoosY]

Does your mac use arm architecture?

[david-antiteum]

Yes, I did the compilation in a Mac with a M1. The trick by @autoantwort from case #17344 works.

BTW, after doing the installation of gRPC, plugins are under x64-osx and, when compiling for arm64-osx they are not found ( find_program( GRPC_CPP_PLUGIN grpc_cpp_plugin ) ).

I did a symlink x64-osx/tools/grpc -> arm64-osx/tools/grpc to bypass the problem.

[JackBoosY]

@strega-nil We have discussed this issue, and I think we should change the code to automatically determine the default triplet in response to changes in the mac architecture.

Already done in microsoft/vcpkg-tool#23. But not yet released in a new version

[NancyLi1013]

The changes in microsoft/vcpkg-tool#23 have been released to new version in vcpkg master branch now.

@david-antiteum Could you please update to the latest vcpkg via git pull and run .\bootstrap-vcpkg.sh to try again?

[Adela0814]

The fix has been released. please get the latest version and try again.
