Python pupil_Apriltags : Problem with DLL path "Could not find module"

Hello I have a problem with pupil_apriltags in python. I have been searching for more than 1 week and tried multiple solutions but none of them worked.

My problem is not with the import of the librairy but when I try to create the detector. There is a reference to a xxxx.dll file (I think) which does not work.

My code

Very simple

from pupil_apriltags import Detector
import cv2
import numpy as np


at_detector = Detector(families='tag36h11',
                       nthreads=1,
                       quad_decimate=1.0,
                       quad_sigma=0.0,
                       refine_edges=1,
                       decode_sharpening=0.25,
                       debug=0)

My error
