 The properties declared on a `template` are the same as the ones you use for targets. The only exceptions are:
 
 - `add-function`: Specifies a custom add function. Projects like [pybind11](https://pybind11.readthedocs.io/en/stable/cmake/index.html#new-findpython-mode) have their own `add_xxx` function, which you can specify here.
+- `add-arguments`: Arguments to pass to the `add-function` before the list of sources. See [cmake_parse_arguments](https://cmake.org/cmake/help/latest/command/cmake_parse_arguments.html) for more details.
 - `pass-sources`: Pass sources directly to the add function instead of using `target_sources`.
