This proved to be helpful for previous protocol experiments, so let's upstream it. Inspired by the corresponding code in Weston. Protocols need to be placed in a `protocols` subdirectory and can be declared in the following way in `meson.build`: ``` ['color-management-v1', 'internal' ], ``` Note the `v1` being part of the name.
