OpenCV and python/virtualenv?

Question

I'm working on a project in python that uses OpenCV (2.3.1), among other libraries. So far, I just apt-get installed everything, but now I want to share my code with someone that might not have everything installed already. So, virtualenv seems like the perfect solution, but I get this.

$ python src/importcv.py # does nothing but import cv, no problems
$ virtualenv .           # create virtualenv here
$ source bin/activate    # activates this virtualenv
(p)$ python src/importcv.py
Traceback (most recent call last):
  File "src/test.py", line 1, in <module>
    import cv
ImportError: No module named cv

Was there something wrong in how I set up the virtualenv, or do I have to do some other step so it can see my opencv python bindings?

Simply copy of the cv2*.so file to the site-packages folder of the virtual environment. For example:

cp /usr/lib/python3.6/dist-packages/cv2.cpython-36m-aarch64-linux-gnu.so ~/your_virt_env_folder/YOUR_VIRT_ENV_NAME/lib/python3.6/site-packages/
