Does Opencv4Tegra use NPP for optimization ?

There is a lot of literature on different optimized image processing and general matrix manipulation libraries.

Examples :

Opencv4Tegra
NPP
Vision Works

I am more interested in knowing if Opencv4Tegra already is binded with NPP and Vision Works for its underlying performance boost ? Like OpenCv makes use of IPP on desktop systems.

If not then I plan to mix up OpenCv with NPP for extra boost in some cases. Does it make sense ?
