   GN optionally generates files for IDE. Possibilities for <ide options>
 
   --ide=<ide_name>
       Generate files for an IDE. Currently supported values:
       "eclipse" - Eclipse CDT settings file.
       "vs" - Visual Studio project/solution files.
              (default Visual Studio version: 2015)
       "vs2013" - Visual Studio 2013 project/solution files.
       "vs2015" - Visual Studio 2015 project/solution files.
+      "vs2017" - Visual Studio 2017 project/solution files.
       "xcode" - Xcode workspace/solution files.
       "qtcreator" - QtCreator project files.
       "json" - JSON file containing target information
 
   --filters=<path_prefixes>
       Semicolon-separated list of label patterns used to limit the set of
       generated projects (see "gn help label_pattern"). Only matching targets
       and their dependencies will be included in the solution. Only used for
       Visual Studio, Xcode and JSON.
