You have modified or added at least one portfile where deprecated functions are used.

If you feel able to do so, please consider migrating them to the new functions:
vcpkg_install_cmake -> vcpkg_cmake_install (from port vcpkg-cmake)
vcpkg_build_cmake -> vcpkg_cmake_build (from port vcpkg-cmake)
vcpkg_configure_cmake -> vcpkg_cmake_configure (Please remove the option PREFER_NINJA) (from port vcpkg-cmake)
vcpkg_fixup_cmake_targets -> vcpkg_cmake_config_fixup (from port vcpkg-cmake-config)

In the ports that use the new function, you have to add the corresponding dependencies:

{
  "name": "vcpkg-cmake",
  "host": true
},
{
  "name": "vcpkg-cmake-config",
  "host": true
}

The following files are affected:

• ports/graphviz/portfile.cmake

LGTM, thanks for your PR!

Noted that graphviz passed with x86-windows x64-windows, x64-osx and x64-linux in CI testing, it cascaded with others triplets(x64-windows-static, x64-windows-static-md, x64-uwp, arm-uwp and arm64-windows) due to the dependency port pango and getopt cascaded.

In my experience graphviz is generally only used in tool form rather than as a library, making it a somewhat poor fit for the builtin catalog. Do you @Ace314159 do you have example(s) using it as a library rather than as a tool?

(Note that we have rejected attempts to add gcc before for similar reasons even though we have llvm because llvm is often used as a library while gcc is not)

[Ace314159]

@BillyONeal Graphviz is a dependency for Gazebo, which is an important simulation library commonly used with ROS2. This will make building Gazebo and using it much easier when using ROS2 on Windows.
