vcpkg doesn't generate valid manifests and configuration files.

Xmake Version

Operating System Version and Architecture

Windows 11

Describe Bug

xmake doesn't create valid stub vcpkg.json and vcpkg-configuration.json files, which doesn't make integration seamless. I often have to manually edit and/or modify vcpkg installation to make it work with calls made from xmake.

looking at the code, it doesn't seem to follow vcpkg schemas

vcpkg.schema.json

vcpkg-configuration.schema.json

for example, I'm unable to set "default-registry" value.

it would be nice to support those files out of the box, or at least provide a way to provide custom settings for both of them

Expected Behavior

I'd like to be able to more precisely control the output of both vcpkg.json and vcpkg-configuration.json because of the registries and overlays.

For example, a project I use vcpkg as a manifest provides "default-registry" key for configuration file, and it isn't supported by xmake.

Project Configuration

function vcpkg(name, configs)
  if not configs then
    configs = {}
  end

  -- Must match a release commit from https://github.com/microsoft/vcpkg/
  local baseline = "511d74f695bd45959d12b50b00f1b68f69e8f0b0"

  configs["baseline"] = baseline

  -- Will cause trouble
  -- configs["default_registries"] = {
  --   kind = "git",
  --   baseline = baseline,
  --   repository = "https://github.com/microsoft/vcpkg"
  -- }

  configs["registries"] = {
    {
      kind = "artifact",
      location = "https://github.com/microsoft/vcpkg-ce-catalog/archive/refs/heads/main.zip",
      name = "microsoft"
    }
  }

  add_requires("vcpkg::" .. name, {
    alias = name,
    configs = configs,
  })
end

vcpkg("asio")

-- ...

Therefore, use packages from the xmake-repo repository as much as possible.
