Ort dylibs providers not bundled

[Omicronlawful]

Bug Description

The execution providers which will be copied into the target folder when building will not be bundled. I believe the issue is that the libs are not required. It links depending on if cuda is available

Your maturin version (maturin --version)

1.9.1

Your Python version (python -V)

3.13

Your pip version (pip -V)

25.1.1

What bindings you're using

pyo3

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Steps to Reproduce

1. add ort with cuda feature to your cargo.toml
2. build

I believe the issue is that the libs are not required.

You mean the dylib does not depend on these execution provider dylibs? In that case maturin won't know they are required to bundle. Consider use auditwheel instead since it has more customized options.
