I have a python package, which I can pip install. I am trying to wrap it using PythonCall. My python package has a pyproject.toml file and it has scipy as one of its dependencies. The latest scipy seems to need a version of GLIBCXX\_3.4.30, but the add or using statements do not seem to bring in the required CXX dependencies for scipy. Is there something I am missing? Do I need a special build script?

My CondaPkg.toml file in the Julia package looks like this

```julia
 [pip.deps]
hello_python = "@ <url to repo>/_git/HelloPython"

```

My pyproject.toml looks like

```julia
[build-system]
requires = [
    "setuptools",
    "setuptools-scm",
    "wheel"
    ]
build-backend = "setuptools.build_meta"

[project]
name = "hello_python"
version = "0.0.1"
description = "A small example package"
classifiers = [
    "Programming Language :: Python :: 3"
    ]

dependencies = [
    'numpy',
   'scipy'
    ]

```

GLIBC is usually provided by your system and not Julia or Python. You can check yours on a terminal with `ldd --version`
