No, it's an aggregation which is fine. In more detail: packaging gpl and non gpl software next to each other is fine, even if your package format is a single binary. Linking mkl into gpl software and distributing the binary would not be okay because you don't have source to mkl you can give people (mkl has binary blobs). When you link software like this, you need to be able to distribute the combined binary under gpl, and unless mkl has changed, you can't. It would be fine to link it and use it locally of course, just not distribute it.
