Description:

I encountered an error while compiling a Rust project using winit version 0.30.7. The error message indicates that the platform is not supported by winit. Here is the error log:

     = note: this error originates in the derive macro `PartialEq` (in Nightly builds, run with -Z macro-backtrace for more info)

Steps to Reproduce:

Clone the repository and navigate to the project directory.
Run the command: cargo run --release -p egui_demo_app.
Observe the compilation error as described above.

Expected Behavior:

The project should compile successfully without any platform-related errors.
Additional Information:

Rust Version: 1.80.0
winit Version: 0.30.7
Operating System: Linux

specify feature you want to build(x11/wayland) and don't spam issue tracker with the same thing in like 3 places, thanks.

Might also be useful to provide the output from running the command rustc -vV, in case the above doesn't work
