【问题描述】：
我正在尝试在 macOS Big Sur 11.6（Apple M1 芯片）上运行来自 https://www.lwjgl.org/guide 的示例代码。我导入了所有必要的库并在 VM 选项中写了-XstartOnFirstThread 并得到了这个错误：
[LWJGL] Failed to load a library. Possible solutions:
a) Add the directory that contains the shared library to -Djava.library.path or -Dorg.lwjgl.librarypath.
b) Add the JAR that contains the shared library to the classpath.
[LWJGL] Enable debug mode with -Dorg.lwjgl.util.Debug=true for better diagnostics.
[LWJGL] Enable the SharedLibraryLoader debug mode with -Dorg.lwjgl.util.DebugLoader=true for better diagnostics.
Exception in thread "main" java.lang.UnsatisfiedLinkError: Failed to locate library: liblwjgl.dylib

at com.company.HelloWorld.run(HelloWorld.java:23)
at com.company.HelloWorld.main(HelloWorld.java:113)
我尝试从其他 jars 中手动提取本地人到项目文件夹中的单独“native/”文件夹，并将-Dorg.lwjgl.librarypath=native 作为 VM 选项传递，但它完全没有改变。我不知道是否应该将“native/”文件夹添加到库中，但它似乎也对结果没有影响。
这是来自 LWJGL 网站的示例代码：

@KaiBurjack “必要”是指在此代码中使用的那些，“导入”是指我通过转到文件 > 项目结构 > 库 > 新项目库 (+符号）> Java 并选择带有 jar 的文件夹。如何添加类路径？
