When writing vcpkg.json for a top-level project, I got the following error:
error: this vcpkg instance requires a manifest with a specified baseline in order to interact with ports. Please add 'builtin-baseline' to the manifest or add a 'vcpkg-configuration.json' that redefines the default registry.
What does baseline mean? I tried looking up the docs, and apparently it refers to a Git repo hash and is used for versioning, but what exactly does this mean? Wasn't able to find any details about this.
From versioning docs:
Baselines define a global version floor for what versions will be considered.
It's really nothing more than a git commit hash in a git registry (builtin registry aka vcpkg git repository is itself a git registry). Vcpkg uses it to extract version information for a port from baseline.json.
For example, if we wanted to install qtbase:
4bee3f5aae7aefbc129ca81c33d6a062b02fcf3b vcpkg would look at baseline.json@4bee3f5aae7aefbc129ca81c33d6a062b02fcf3b and find qtbase@6.6.1#10.11afcc7e8b7118f3a0ae97140ce8037b7f53ad64 vcpkg would look at baseline.json@11afcc7e8b7118f3a0ae97140ce8037b7f53ad64 and find
qtbase@6.3.2#3.
