Description

Title: "Issue Generating Wheel for OpenCV on macOS"

Description:
I am switching to mac and,
I am trying to build OpenCV on macOS, and I encountered an issue when generating a wheel for OpenCV. Here's the context and the problem I'm facing:

Problem:
When I attempt to build OpenCV from source, I get to the point where I need to generate a wheel for OpenCV. However, the build process for fails with an error. I've tried the following steps:

  1. Cloned the OpenCV repository and followed the build process as outlined in the official documentation.

  2. At the wheel generation step, I run the following command:

    python setup.py bdist_wheel
    

Error Message:

 Problem with the CMake installation, aborting build. CMake executable is cmake
  ----------------------------------------
  ERROR: Failed building wheel for opencv-python
Failed to build opencv-python

Expected Behavior:
I expect the wheel to be generated successfully without errors.

Additional Information:

  • I have already installed Xcode and Xcode Command Line Tools.
  • My development environment is set up with the necessary dependencies.
  • I have tried building OpenCV with both Python 3.11 and Python 3.12 with the same result.

Question:
What could be causing this error during the wheel generation for OpenCV on macOS, and how can I resolve it? Are there any specific configuration or dependency requirements I might be missing?

I appreciate any guidance and suggestions to help me successfully build OpenCV on macOS. Thank you in advance for your assistance.

Research direction

Start by reviewing the repository's official build documentation and the setup.py bdist_wheel invocation on macOS. Reproduce the CMake installation failure with Python 3.11 or 3.12, then inspect the build output to identify the missing configuration or dependency. Done means the cause is documented and the wheel builds successfully, with a focused test or reproduction if the repository provides one.
