How to get pip to automatically install local wheel dependencies

Question

I've built a gizmo wheel which has a dependency on an internally developed (transfunctioner) wheel which is not available on a public PyPy server. The external dependencies are automatically downloaded and installed, however I am unable to find a way to get the local wheel to be installed, despite my best attempts as shown in the my pyproject.toml extract below:

[project]
name = "Gizmo"
version = "1.5.0"
requires-python = ">=3.9"
dependencies = [
    "pycairo~=1.21.0",
    "PyGObject~=3.42.0",
    "PyGObject-stubs~=1.0.0",
    "acme_transfunctioner>=1.3.0"
]

[tool.setuptools.packages.find]
where = ["."]

[tool.poetry.dependencies]
pycairo="^1.21.0"
PyGObject="^3.42.0"
PyGObject-stubs="^1.0.0"
acme_transfunctioner = { version = ">=1.3.0", file = "dist/depend/acme_transfunctioner-1.3.0-py3-none-any.whl" }

Error message:
