This extension is provides integration with the clang-include-fixer command line tool to query and add includes for missing C++ symbols.
This extension expects clang-include-fixer to be available and configured. With that in place, just invoke the 'clang-include-fixer' command from the command palette. It will let you choose which include file to insert.
Please refer to the clang documentation for details on how to set up clang-include-fixer.
If 'clang-include-fixer' is not on your path, you can specify a full path or different binary in your user settings via:
"clang-include-fixer.binary": "/path/to/clang-include-fixer"
