how to write ‘@’ in `configure_file( "@" @ONLY )` ?

`input_file` has the following content:

```auto
@

```

I tried `configure_file( "input_file" @ONLY )` but am receiving `\@`.

I think the easiest solution is to create a CMake variable containing the at-sign and use it:

```
set(AT @)
configure_file("@AT@" @ONLY)
```
