Windows-GNU.cmake needs minor update to support Visual Studio 2019

I needed this small diff to use Windows-GNU.cmake with Visual Studio 16 2019:

    # Query the VS Installer tool for locations of VS 2017 and above.
    set(_vs_installer_paths "")
+    foreach(vs RANGE 16 15 -1) # change the first number to the largest supported version
-    foreach(vs RANGE 15 15 -1) # change the first number to the largest supported version
      cmake_host_system_information(RESULT _vs_dir QUERY VS_${vs}_DIR)
      if(_vs_dir)
        list(APPEND _vs_installer_paths "${_vs_dir}/VC/Auxiliary/Build")

• Is there a larger VS2019 effort that can absorb this small change?
• This diff is against cmake-3.16.2
