Build backend error during `rye sync`

[chainyo]

Steps to Reproduce

I'm trying to install cugraph dependencies with extra sources and I'm getting an error which doesn't look super comprehensive to me.

1. rye init --lib foo
2. rye pin 3.9.18
3. Add the following to your pyproject.toml

[[tool.rye.sources]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu118"
type = "index"

[[tool.rye.sources]]
name = "cugraph-cu12"
url = "https://pypi.nvidia.com"
type = "index"

[project.optional-dependencies]
cpu = ["torch==2.0.1"]
gpu = [
    "cugraph-cu12==24.2.0",
    "torch==2.0.1"
]

4. rye sync --features gpu

Expected Result

A good synchronization of the environment and the lock files. It works while using traditional pip install with the extra indexes.

Here is the pyproject.toml of the cugraph project. If I understand well they are using a custom build backend with setuptools. It might be a dependency problem?

Actual Result

It's crashing during the generation of the lock file:

rye sync --features gpu

Any hints on how to solve this Build backend failed to determine extra requires with build_wheel() error?
