//examples/hello_world-rs/ta/build.rs
```rust
use proto;
use optee_utee_build::{TaConfig, RustEdition, Error};
use optee_utee_sys::TA_FLAG_USER_MODE;
use optee_utee_sys::TA_FLAG_EXEC_DDR;

let flags: u32 = TA_FLAG_USER_MODE |

let config = TaConfig::new_default_with_cargo_env(proto::UUID)?
.ta_flags(flags);
optee_utee_build::build(RustEdition::Before2024, config)
}
```
**I want use optee_utee_sys::TA_FLAG_xxx to specify my TA_FLAGS.But had
blow errors.**
