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

[jesseclin]

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 = "Nic30original@gmail.com"},
]
classifiers = [
"Development Status :: 4 - Beta",
"Intended Audience :: Developers",
"License :: OSI Approved :: MIT License",
"Operating System :: OS Independent",
"Programming Language :: Python :: 3",
"Programming Language :: Python :: 3 :: Only",
"Programming Language :: Python :: 3.10",
"Programming Language :: Python :: 3.11",
"Programming Language :: Python :: 3.12",
"Programming Language :: Python :: 3.7",
"Programming Language :: Python :: 3.8",
"Programming Language :: Python :: 3.9",
"Topic :: Scientific/Engineering :: Electronic Design Automation (EDA)",
"Topic :: System :: Emulators",
"Topic :: System :: Hardware",
"Topic :: Utilities",
]
dependencies = [
"hdlConvertorAst>=1.0",
"hwtSimApi>=1.3",
"ipCorePackager>=0.6",
"natsort>=8.4.0",
"pyDigitalWaveTools>=1.1",
]
license = {text = "MIT"}
requires-python = ">=3.12"

[project.urls]
Homepage = "https://github.com/Nic30/hwt"

@jesseclin thank you for your contribution, currently i am working day and night to finish hwtHls, I have about 500 comits for hwt as well.

Can you also post the error message for pip >=v25 ? So I can verify installation behavior when the time come?
