+On Windows, vcpkg builds packages in a special clean environment that is isolated from the current command prompt to
+ensure build reliability and consistency. This triplet option can be set to a list of additional environment variables
+that will be added to the clean environment. The values of these environment variables will be hashed into the package
+abi -- to pass through environment variables without abi tracking, see `VCPKG_ENV_PASSTHROUGH_UNTRACKED`.
See also the `vcpkg env` command for how you can inspect the precise environment that will be used.
