The PR does not touch any vcpkg-related code. Could the issue be that the Github environment has changed?

Posting here below the link where I asked how to fetch the required data to append to the key in order to tie the cache to a given environment version. Probably the environment and the version would be good candidates (e.g Environment: macos-10.15 Version: 20201212.1), as I expect them to change on updates.

@vadi2 I took a quick look, but i think it is a good lead: the cache has been created in the past with a different version of the macOS GitHub environments, and the vcpkg executable is failing its execution on some missing binary dependency, i.e. dyld: Symbol not found: ___emutls_v._ZSt11__once_call.

The environment look brand new released on 10th Jan 2021.

Environment: macos-10.15
Version: 20210110.1
Included Software: https://github.com/actions/virtual-environments/blob/macOS-10.15/20210110.1/images/macos/macos-10.15-Readme.md

The solution is to change the key, so that the old cache is not used anymore, and vcpkg’s executable is being rebuilt.

I think the action should include by default the version of the image, but I am not aware of any way to fetch it. We can keep this ticket open until i found a good solution to this problem.
