You can globally share compile artifacts by setting a global target directory in the global Cargo config.
In $HOME/.cargo/config.toml:
[build]
target-dir = "/path/to/dir"
The only problems I had when I did it where some cargo plugins and some dependencies with build.rs files that expected the target folder in it's usual location.
Idk, maybe you can share the common packages across projects. (That can never go wrong, right? /s)
Sources are shared, sharing compile-time artefacts is done within workspaces.
Oh… I did mean sharing comptime artifacts
