At PixLab, we believe this is the right approach to license SDKs & C Libraries. We did this with our embedded Computer Vision Library (https://pixlab.io/downloads) and it did works quite well.
Corporations really hate anything GPL related and will ultimately purchase commercial licenses at high cost to get rid of GPL if they are interested enough in your product.
Note that dual licensing was first popularized by Sleepycat software makers of BerkeleyDB now absorbed by Oracle. They were profitable during their short lifespan thanks to this approach.
