rustc version: rustc 1.78.0 (9b00956e5 2024-04-29)

editor or extension: VSCode

repository link (if public, optional):
https://github.com/DiscreteTom/rust-analyzer-include-issue

code snippet to reproduce:

// see the repo above for more details
include!("../../snippet.rs");

fn main() {
    println!("{}", snippet());
}

Got error:

failed to load file `../../snippet.rs`rust-analyzer[macro-error](https://rust-analyzer.github.io/manual.html#macro-error)

However this is compile-able and runable by cargo build or cargo run.

Unfortunately a known issue. I'll close this as a dupe of #17040.
