Vapoursynth: How to getting BilateralGPU to work?

[Selur]

I stumbled over the BilateralGPU filter (https://github.com/WolframRhodium/VapourSynth-BilateralGPU) while looking at a GradFun3Mod variant (https://github.com/Irrational-Encoding-Wizardry/fvsfunc) I wanted to test.
It mentions 'needs OpenCV 3.2 with CUDA module'. Over at https://jamesbowley.co.uk/downloads/#v3.2 I found a OpenCV 3.2 with CUDA for VS2015.
Copying the opencv_world320.ddll next to the bilateralGPU.dll didn't solve the problem of the script not working, so I tried loading the dll explicitly using:

# Imports
import os
import sys
import vapoursynth as vs
core = vs.get_core()
import ctypes
# Loading Support Files
Dllref = ctypes.windll.LoadLibrary("G:/Hybrid/64bit/vsfilters/Support/BilateralGPU/opencv_world320.dll")

that gave me:

Failed to evaluate the script:
Python exception: [WinError 126] Das angegebene Modul wurde nicht gefunden

Traceback (most recent call last):
  File "src\cython\vapoursynth.pyx", line 1847, in vapoursynth.vpy_evaluateScript
  File "H:\Temp\tempPreviewVapoursynthFile12_42_42_586.vpy", line 8, in <module>
    Dllref = ctypes.windll.LoadLibrary("G:/Hybrid/64bit/vsfilters/Support/BilateralGPU/opencv_world320.dll")
  File "ctypes\__init__.py", line 422, in LoadLibrary
  File "ctypes\__init__.py", line 344, in __init__
OSError: [WinError 126] Das angegebene Modul wurde nicht gefunden

-> Did any one try BilateralGPU for Vapoursynth and can tell me how to get it working?
