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.
Sources are shared, sharing compile-time artefacts is done within workspaces.
Oh… I did mean sharing comptime artifacts
