Cound't find "org_lwjgl_openal_AL.h' when building boardwalk-lwjgl jni by NDK.

我正在尝试通过Android NDK编译您的LWJGL2.9.1项目，但是遇到了一些问题。
由于我使用的是Windows操作系统，所以我对原项目的Android.mk进行了修改
但是在编译的时候，出现了错误

@longjunyu2 Did you build lwjgl with ant first? The Java part of LWJGL needs to be built with ant first to generate the native headers.

I haven't touched this in like four years, so sorry if something broke in the meantime.

[longjunyu2]

@zhuowei 谢谢您的回答。在此之前我没有使用ant进行build。我将会再次尝试的，谢谢。:)

@longjunyu2 Also, I built this on Ubuntu 14.04 - if something breaks, you might want to try building on Linux or Windows Subsystem for Linux.
