   `target_env = "sgx"`
   It does not mean that you are currently in the SGX environment.
   It is defined in the target specification file of the custom SGX target and is used by xargo to build the sysroot of the SGX target.

   `#[cfg(not(target_env = "sgx"))]`
   Use `cfg` to check if your enclave is being compiled with the sysroot of the SGX target.
