OUT_DIR not set even though build scripts exists!

help
1

I have 2 similar projects using OUT_DIR one of them works fine while the other doesn't.
Project 1 which works fine, but my own copy structured similarly like

├── build.rs
├── Cargo.lock
├── Cargo.toml
├── src
│   ├── lib.rs
│   ├── model
│   │   ├── mnist.onnx
│   │   └── mod.rs
│   └── state.rs

cargo build fails with the error :

error: environment variable `OUT_DIR` not defined at compile time
 --> src/model/mod.rs:2:22
  |
2 |     include!(concat!(env!("OUT_DIR"), "/model/mnist.rs"));
  |                      ^^^^^^^^^^^^^^^
  |

So the build.rs file exists but it seems that cargo cannot detect it? Any ideas why? Also possible solutions?

Is bulid a typo in the actual file name or just the visual?

Wow, It seems that was the issue. Now facing another one, will mark as solved once it all works. Thank you!

Edit: I was thinking over such a silly mistake for 3 days...
