### Clang parser (experimental)
By default Cppcheck uses an internal C/C++ parser. However there is an experimental option 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
the normal Cppcheck format. And then normal Cppcheck analysis is performed on that.
You can also pass a custom Clang executable to the option by using for example `--clang=clang-10`. You can also pass it
with a path. On Windows it will append the `.exe` extension unless you use a path.
