我正在尝试从the ARToolKit5 examples page编译simpleLite.c示例。如果我运行.app文件，它可以正常工作。我想看看我是否可以修改文件中的任何内容，所以我尝试重新制作文件，但是我收到了错误：

该文件夹包含三个文件，makefile.in，.plist文件和.c源代码。 AR/config.h文件夹存在于ARToolKit5存档（ARToolKit5/include/AR）的其他位置。
通常情况下，我假设我需要指定源文件夹中的路径，但还有include语句，如# include <GLUT/glut.h>，这些语句不会抛出错误。
对于C开发我是相当新的/生锈的，所以我不确定甚至可以解决这个问题。谁能指出我正确的方向？我是否需要指定标题路径，还是不太明显？
