22    /// * `base_dir` - The base directory to use for the paths of the libraries in the `.gdextension` file.
23    /// * `lib_name` - Name of the library crate that is being compiled. It can be retrieved with the environmental variable: "`CARGO_PKG_NAME"`, but it must be turned into snake_case.
24    /// * `windows_abi` - Env ABI used to build for `Windows`.
25    /// * `target_dir` - Path to the build folder (specified inside the variable `[build] target-dir` of `.cargo/config.toml`) **relative** to the *`base_dir`*. For example, if the `base_dir` is [`ProjectFolder`](crate::args::BaseDirectory::ProjectFolder), the path for `Godot` would be `"res://path/to/dep"` and the path provided must be `"path/to/build"`. If the path contains non valid Unicode, it will be stored calling [`to_string_lossy`](Path::to_string_lossy).

29    /// The same [`GDExtension`] mutable reference it was passed to it.
