Display a message in the Cargo build output during compilation.

toml [dependencies] build-alert = "0.1"

Example

```rust

[cfg(debug_assertions)]

build_alert::yellow! {" NOTE: use --release Syn's test suite has some tests that run on every source file and test case in the rust-lang/rust repo, which can be pretty slow in debug mode. Consider running cargo test with --release to speed things up. "}

[cfg(not(feature = "all-features"))]

build_alert::red! {" ERROR: use --all-features Syn's test suite normally only works with all-features enabled. Run again with --all-features, or run with --features test to bypass this check. "} ```
