This is a minimal working example package using cysignals.

Building this package is also part of the cysignals testsuite.

On a clear repo, and no cysignals installed anywhere, the following
works:

uv venv
source .venv/bin/activate
uv sync --frozen --inexact -v --no-install-project
uv sync --frozen --inexact -v --no-build-isolation --no-editable --config-settings=builddir=builddir
uv run --no-editable meson test --print-errorlogs -C builddir
