最近在学go的GUI编程，go build 的时候报错了！大佬来看看可好？

go代码如下： ``` 1 │ package main 2 │ 3 │ import ( 4 │ "fyne.io/fyne/app" 5 │ "fyne.io/fyne/widget" 6 │ ) 7 │ 8 │ func main() { 9 │ a := app.New() 10 │ w := a.NewWindow("hello!GUI") 11 │ 12 │ w.SetContent(widget.NewLabel("what?!")) 13 │ w.ShowAndRun() 14 │ } ``` 我go build之后，就提示下面的报错 ``` # pkg-config --cflags -- gl gl Package gl was not found in the pkg-config search path. Perhaps you should add the directory containing `gl.pc' to the PKG_CONFIG_PATH environment variable Package 'gl', required by 'virtual:world', not found Package 'gl', required by 'virtual:world', not found pkg-config: exit status 1 # github.com/go-gl/glfw/v3.3/glfw In file included from ./glfw/src/internal.h:188, from ./glfw/src/context.c:30, from ../../../go/pkg/mod/github.com/go-gl/glfw/v3.3/glfw@v0.0.0-20211213063430-748e38ca8aec/c_glfw.go:4: ./glfw/src/x11_platform.h:36:10: fatal error: X11/Xcursor/Xcursor.h: No such file or directory 36 | #include <X11/Xcursor/Xcursor.h> | ^~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. ``` 就行是什么情况？该怎么解决呢？
