[Python] How to add OpenCV as precompiled library in Poetry?

I am trying to add OpenCV to my virtual environment with Poetry. OpenCV is already installed globally and can be used globally in python, but not in a virtual environment created by Poetry.

I added the library to poetry like this:

[tool.poetry.dependencies]
cv2 = { path = "/usr/local/lib/python3.8/site-packages/cv2/python-3.8/cv2.cpython-38-aarch64-linux-gnu.so" }


When trying to install it with poetry install I get the following error message:

ReadError

file could not be opened successfully

at /usr/local/lib/python3.8/tarfile.py:1608 in open
1604│ except (ReadError, CompressionError):
1605│ if fileobj is not None:
1606│ fileobj.seek(saved_pos)
1607│ continue
→ 1608│ raise ReadError("file could not be opened successfully")
1609│
1610│ elif ":" in mode:
1611│ filemode, comptype = mode.split(":", 1)
1612│ filemode = filemode or "r"


How can I add globally installed precompiled libraries to my poetry environment?
