How about adding pyproject.toml for local directory installation with the newer version of pip (>=v25) ?

For example:

[build-system]
requires = ["pdm-backend"]
build-backend = "pdm.backend"

[project]
name = "hwt"
version = "3.8"
description = "A library for a construction and analysis of digital circuits"
readme = "README.md"
authors = [
{name = "Michal Orsak", email = "[email protected]"},
]
classifiers = [

"Operating System :: OS Independent",

"Programming Language :: Python :: 3 :: Only",

"Topic :: System :: Emulators",
"Topic :: System :: Hardware",

]
dependencies = [

"ipCorePackager>=0.6",

"pyDigitalWaveTools>=1.1",
]

requires-python = ">=3.12"
