    :param source_dir: The path to the source directory, containing
        pyproject.toml.
    :param build_backend: The build backend spec, as per PEP 517, from
        pyproject.toml.
    :param backend_path: The backend path, as per PEP 517, from pyproject.toml.
    :param runner: A callable that invokes the wrapper subprocess.
    :param python_executable: The Python executable used to invoke the backend

    The 'runner', if provided, must expect the following:

    - cmd: a list of strings representing the command and arguments to
      execute, as would be passed to e.g. 'subprocess.check_call'.
    - cwd: a string representing the working directory that must be
      used for the subprocess. Corresponds to the provided source_dir.
    - extra_environ: a dict mapping environment variable names to values
      which must be set for the subprocess execution.
