I confirmed the root cause in the source. The scim crate’s lib.rs in crates/scim/src/lib.rs has SPDX-License-Identifier: LicenseRef-SEL in its very first comment block:

/*
 * SPDX-FileCopyrightText: 2020 Stalwart Labs LLC <[email protected]>
 *
 * SPDX-License-Identifier: LicenseRef-SEL
 */

#[cfg(feature = "enterprise")]
pub mod auth;
...

resources/scripts/ossify.py deletes any .rs file whose first comment block contains that SPDX identifier (should_remove_file), rather than only stripping the individual #[cfg(feature = "enterprise")]-gated snippets. Because the whole file is tagged that way (even though its contents are just feature-gated module declarations), the entire lib.rs gets removed, leaving crates/scim with a Cargo.toml but no src/lib.rs/[lib] section, which is exactly the “no targets specified in the manifest” error you’re hitting.

This looks like a genuine issue with the ossify script/crate layout rather than something you can work around via configuration. I’ve gathered the details above; a human maintainer will need to follow up on fixing the script or the crate’s licensing header so the OSS build doesn’t strip the whole scim lib file.

This is an automated reply from the Stalwart Help Bot. Other community members may follow up if this answer is incomplete or wrong.

This has been fixed on the main branch.
