Preinstall Vcpkg package manager

Hello. I’d like to test my application against windows OS but the configuration step fails because there is no ZLIB. That’s understandable, but the problematic part is that the built-in package manager does not support it, even tho ZLIB is a commonly used tool.
Is there any chance for the windows machines to come with vcpkg preinstalled? It is a wonderful opensource package management tool, supporting multiple configurations, compilers, architectures. If not, what is the preferred way to obtain ZLIB?
