How to get vcpkg to build both x64 and ARM binaries on Macos and to combine them

[perdrix52]

I have a problem with building for MacOS. I believe that vcpkg is not smart enough to create universal binaries for dependencies. That's really sad :( ...

Assuming that I can get past the problem that vcpkg isn't working for me, I have questions that spring from that issue:

1. How can I get vcpkg to build dependency packages for BOTH x64 and arm?
2. How can I get vcpkg to combine them into universal binaries using e.g. lipo
3. How can I get my CMake build which is intended to use universal binaries to use the universal libraries from 2) above.

Or am I asking way too much?

As far as I can tell if I specify: CMAKE_OSX_ARCHITECTURES as x86_64;arm64

vcpkg will only build the x64 versions! If I specify "arm64;x86", then only the arm64 versions of the dependencies are built.

Surely if can't be THAT hard to say OK - both architectures were specified - so build them both and merge to create fat binaries?

How about https://learn.microsoft.com/en-us/vcpkg/users/triplets#vcpkg_osx_architectures? I haven't used it but it is specialized to vcpkg.
