Build option to dynamically set abi3 version #1894
Description
Currently the way to set abi3 version is via applying a versioned-feature in Cargo.toml (e.g., abi3-py312).
I'm requesting a way set that at the CLI. The reason for this is to be able to build wheels targeting multiple abi3 versions from the same source.
We're currently able to do this with setuptools-rust with the following command:
if [ -n "${{ matrix.PYTHON.ABI_VERSION }}" ]; then
PY_LIMITED_API="--config-settings=--build-option=--py-limited-api=${{ matrix.PYTHON.ABI_VERSION }} --no-build-isolation"
fi
OPENSSL_DIR="/opt/pyca/cryptography/openssl" \
OPENSSL_STATIC=1 \
.venv/bin/python -m pip wheel -v $PY_LIMITED_API cryptograph*.tar.gz -w dist/ && mv dist/cryptography*.whl tmpwheelhouse
