Hello,
I am trying to troubleshoot an error that pops up when trying to use rust-analyzer in VSCode on a project that has a complex build system.
I got pretty far into configuring rust-analyzer for VSCode (and generating configurations). But I'm getting stuck on this error that seems to be related to the defmt crate and its macros:

proc-macro crate build data is missing dylib path

This error diseappiears when I remove ariel-os/defmt from the enabled features in the rust-analyzer config.

I created a repository to recreate the issue here: github.com/nponsard/ariel-os-vscode-config-troubleshooting

Here's how you can replicate the issue:

• clone the repository
• open it in VSCode (you can use the devcontainer configuration)
• install the dependencies ./install-deps.sh
• restart rust-analyzer
• open src/main.rs and wait for it to finish scanning the project
• once rust-analyzer finished scanning, try to jump to the definition of the info!() macro line 8
• the error should appear and propagate back to main.rs "proc-macro crate build data is missing dylib path"

Do you have any idea how to troubleshoot this further ?

Thanks
