MacOS setup.py build failing after successful build of wallet-core

[idan-krayon]

ProductName: macOS ProductVersion: 12.4 BuildVersion: 21F79 Python version number 3.9.10 Apple clang version 13.1.6 (clang-1316.0.21.2.5) Target: arm64-apple-darwin21.5.0

I followed these steps:

1. https://github.com/phuang/wallet-core-python#readme
2. https://developer.trustwallet.com/wallet-core/developing-the-library/building - MacOS

The wallet-core build was successful but the 'python setup.py build' failed:
