  hello, I cant compile simple app with glad

   libs/csfml/csfml
  import libs/glad/gl
  
  
  
  var window = newRenderWindow(videoMode(500, 500), "OpenGL")
  window.verticalSyncEnabled = true
  
  if(not gladLoadGL()):
    echo "error loadeng opengl"
  
  var event: Event
  while window.open:
    while window.pollEvent(event):
      case event.kind
        of EventType.Resized:
          glViewport(0, 0, event.size.width, event.size.height)
        of EventType.Closed:
          window.close()
        else: discard
    
    window.clear Black
    window.display()
  
  window.destroy()
  Run

  compiler writes:

          ... libs\glad\gl.nim(2103, 6) Hint: 'gl.hasExt(extname: string)[declared in libs\glad\gl.nim(2103, 5)]' is declared but not used [XDeclaredButNotUsed]

  if(not gladLoadGL()):

  type mismatch: got <>

  How does your gladLoadGL proc look like?

  your gladLoadGL definition is proc gladLoadGL(load: proc): bool but you invoked gladLoadGL() without argument

  import dynlib
  let GLlib = loadLib("opengl32.dll") # Windows OS only
  proc GetGLSymbolAddr(symbol: string): pointer = GLlib.symAddr(symbol)
  
  var window = newRenderWindow(videoMode(800, 600), "OpenGL")
  window.verticalSyncEnabled = true
  
  if(not gladLoadGL(GetGLSymbolAddr)):
    echo "error loading opengl"
  Run

  thank me later
