4. Select the package flavor which you wish to build with`ENABLE_CONTRIB` and`ENABLE_HEADLESS`: i.e.`export ENABLE_CONTRIB=1` if you wish to build`opencv-contrib-python`

5. Run``pip wheel . --verbose``. NOTE: make sure you have the latest``pip`` version, the``pip wheel`` command replaces the old``python setup.py bdist_wheel`` command which does not support``pyproject.toml``.

- this might take anything from 5 minutes to over 2 hours depending on your hardware

6. Pip will print freshwill location at the end of build procedure. If you use old approach with`setup.py` file wheel package will be placed in`dist` folder. Package is ready and you can do with that whatever you wish.

- Optional: on Linux use some of the`manylinux` images as a build hosts if maximum portability is needed and run`auditwheel` for the wheel after build

- Optional: on macOS use``delocate`` (same as``auditwheel`` but for macOS) for better portability
