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 PR contains 2 commits, but I'm going to polish and test 1st one, and then add the 2nd one.

I've decided to leave libatomic-ops port addition here, and create another PR enabling multi-threading in bdwgc.

Thanks for the PR and awesome library!

I noticed that the CMake package name is "Atomic_ops", so I adjusted the helper calls to correctly account for that name. I now get:

$ vcpkg install libatomic-ops
...
Elapsed time for package libatomic-ops:x64-linux: 703 ms

Total elapsed time: 966.5 ms

The package libatomic-ops provides CMake targets:

    find_package(Atomic_ops CONFIG REQUIRED)
    target_link_libraries(main PRIVATE Atomic_ops::atomic_ops Atomic_ops::atomic_ops_gpl)
