Unable to deploy python program with cx_freeze due to cv2

So I have a fairly large python program that I want to port to other machines (ubuntu 18.04) without having to install all the python packages and dependencies for each machine, I chose to use cx_Freeze for this and it seems to build the project fine into a single executable but the executable crashes when calling cv2.imshow. I managed to reproduce the error with this small snippet of code:

import numpy as np
import cv2
img = cv2.imread('monke.jpg',0)
cv2.imshow("img", img)

this is my cx_Freeze build script:

import sys
from cx_Freeze import setup, Executable

# Dependencies are automatically detected, but it might need fine tuning.
build_exe_options = {"packages": ["os"], "excludes": []}

# GUI applications require a different base on Windows (the default is for
# a console application).

setup(
    name = "test",
    version = "0.1",
    description = "My GUI application!",
    options = {"build_exe": build_exe_options},
    executables = [Executable("cv2_test.py")]
)

and this is the error I get:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/vaki/Desktop/cv2_test/build/exe.linux-x86_64-3.7/lib/cv2/qt/plugins" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

Aborted (core dumped)

I also tried running the program with QT_DEBUG_PLUGINS=1 for a more detailed error output:

Any help/suggestions would be greatly appreciated. I tried using pyInstaller, but it doesn't manage to even build the project.

Solution

So thanks to jpeg from the other answer I managed to fix the issue by adding the following snippet of code to my builds script:

opencv_lib_src = os.path.join(os.path.dirname(cv2.__file__), '..', 'opencv_python.libs')
opencv_lib_dst = os.path.join('lib', 'opencv_python.libs')
build_exe_options = {"packages": ["os"], 
                     "excludes": [],
                     "include_files": [(opencv_lib_src , opencv_lib_dst)]}
