无法使用 FLTK (Rust) 构建项目

问题描述

我正在尝试从 FLTK 的文档中构建和运行一个示例；

use fltk::{app::*,button::*,frame::*,window::*};

fn main() {
    let app = App::default();
    let mut wind = Window::new(100,100,400,300,"Hello,FLTK!");
    let mut frame = Frame::new(0,200,"Boring label");
    let mut but = Button::new(160,210,80,40,"Click me!");
    
    wind.end();
    wind.show();
    
    // Remember: Callbacks after initializing the interface
    but.set_callback(move || frame.set_label("Hello,World!"));
    
    app.run().unwrap();
}

但我收到以下错误：

Compiling fltk-sys v1.0.11

我尝试安装 CMake，但似乎没有帮助。你们能帮我找出我哪里出错了吗？
