### Clang parser
By default Cppcheck uses an internal C/C++ parser. However it is possible to use the Clang parser instead.
Install `clang`. Then use Cppcheck option `--clang`.
Technically, Cppcheck will execute `clang` with its `-ast-dump` option. The Clang output is then imported and converted into our normal Cppcheck format. And then normal Cppcheck analysis is performed on that.
