There isn't really a right way or a wrong way.

You can do it via '-Dfoo=bar' in c_args, like my meson.build had
already for PACKAGE and VERSION.

Or you do it like you're proposing by writing a config.h file from
configuration_data(). You still need a

  configure_file(output : 'config.h', configuration : conf_data)

somewhere then, and may also need to add '-DHAVE_CONFIG_H' to c_args.

Cheers
