# GNUstep make and NEEDS_GUI
By default, GNUstep make encodes assumptions about whether it should link your target to the GUI framework ([`libs-gui`](https://github.com/gnustep/libs-gui) on most platforms, `AppKit` on macOS). The default is `yes` for apps, and `no` for frameworks, libraries, and tools.

To change this, modify your `GNUmakefile` to set one of these variables to either `yes` or `no`:

- `NEEDS_GUI`: applies to all targets in the `GNUmakefile`.
- `[product_name]_NEEDS_GUI`: applies to the specific product. For example, if your tool is called `MyTool`, and it needs to link to the GUI framework, set `MyTool_NEEDS_GUI = yes`.
