[SOLVED] Cmake problems after upgrading to MacOS 13.0

Issue

As mentioned on the title, CMake seems to be broken after upgrading to MacOS 13.0.

Trying to install something that requires Cmakes takes unusually long then the following pop-up shows up.

“CMake” is damaged and can’t be opened. You should move it to the Trash. 

This file was downloaded on an unknown date.  # this txt is grey and smaller font

Pop-up Options
1. Move to Trash  2. Cancel

Steps to reproduce Err

1. Cloned EasyOCR

   1.1 git clone ...

2. Made Python venv

   2.0. cd EasyOCR/

   2.1. python3 -m venv venv

   2.2. source venv/bin/activate

   2.3. venv info

   python --version && pip --version
   # output   
   Python 3.10.6
   pip 22.3 from ...  # path to venv dir
   

3. pip install -r requirements.txt

# requirements.txt content
torch
torchvision>=0.5
opencv-python-headless<=4.5.4.60
scipy
numpy
Pillow
scikit-image
python-bidi
PyYAML
Shapely
pyclipper
ninja

4. After a while, the aforementioned pop-up, shows up. Clicking on either option will result in the following error.

Building wheels for collected packages: opencv-python-headless
  Building wheel for opencv-python-headless (pyproject.toml) ... error

      Traceback (most recent call last):
      
      Problem with the CMake installation, aborting build. CMake executable is cmake
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for opencv-python-headless
Failed to build opencv-python-headless
ERROR: Could not build wheels for opencv-python-headless, which is required to install pyproject.toml-based projects

Any thoughts on how to fix or get around this? This is the first time I see this pop up.

Solution

The pip package is broken on macOS 13 prior to CMake 3.24.2 due to improper code signing. You should upgrade CMake in your virtual environment by running:

$ python -m pip install -U pip setuptools wheel
$ python -m pip install -U 'cmake>=3.24.2'

As CMake is extremely backwards compatible, it should be safe. You can also add cmake>=3.24.2 to your requirements.txt.
