Correct, the measure looks for daylighting controls -- and illuminance maps, both must be present -- extant in the model, and will perform an annual CBDM on the points found there, using Radiance. There are some measures out there that will place sensors for you, but nothing public that I know of that will do the illuminance maps for you.
Honestly, it makes more sense to do the illuminance points yourself, via measure, after the OSM has been translated to Radiance format. That way you're not constrained to the rectangular inputs like you are with an illuminance map. The illuminance map data is used for daylight metrics, so the more spatially accurate the points, the better.
