Direct force power meters, which are the vast majority in use, use strain gauges - no wind wizardry needed. There's are some meters, like the PowerPod, that infer power by way of incorporating air speed, bike speed, acceleration, slope, etc. I would assume that you'd be able to easily tease out wind speed with one of those devices, but I don't know - meaning I've never looked for it - if that's a data field that head unit manufacturers have embraced/made available.
