You should not depend on python3-config being present if you are in Python - instead, you should use |

- Bump vendored version of boost to 1.87, to enable support for numpy-2. - Bump cibuildwheel version and add a dependabot workflow to keep actions up to date. - Add a fix for macos wheel builds (see pypa/cibuildwheel#2021) - Add python-3.13 to the wheel build matrix. - Change no-as-needed linking option to be based on OS flavor rather than compiler. - Compile libflac as well as boost when building wheels. Bump this vendored version to 1.5.0 which includes threaded compression.

Description
Some more complex C/C++ libraries need
python3-configto get ldflags, include directories, etc.On Linux, because each version of Python is in its own container, this works fine.
On macOS, because
cibuildwheelrelies entirely on virtualenvs and does not put/Library/Frameworks/Python.framework/Versions/{current_version}/binin PATH,python3-configdefaults to the system-wide Python 3.11/3.12 installation. Meaning any non-trivial C/C++ extensions may fail (and not even outright fail to build- wheels produced may fail to import because of missing symbols due to ABI breaks.)A fix to this would be to prepend
/Library/Frameworks/Python.framework/Versions/{current_version}/bintoPATHduring builds.For users currently blocked by this, a possible workaround is adding this in your
