Cocos2dx Android.mk

用之前写过的Android.mk为例（见下面）来讲：

Vuforia-prebuilt模块

第一个模块Vuforia-prebuilt，是将已经编译好的.so以预编译库的形式添加进该工程，模块名为Vuforia-prebuilt，需要注意的是一个模块只能添加一个.so.
LOCAL_EXPORT_C_INCLUDES 是头文件的路径，包含头文件的路径同时，并导出这个路径，意思就是说，如果有个名为A模块需要以LOCAL_STATIC_LIBRARIES的形式添加这个B模块，A模块就不需要添加这个B模块的include的路径，因为B模块的include路径已经以LOCAL_EXPORT_C_INCLUDES的形式一并导出了

OpenCV-prebuilt模块

第二个模块OpenCV-prebuilt，同上

cocos2dcpp_shared模块

第三个模块cocos2dcpp_shared，这是汇总了其他模块的模块，讲到笔记的重点了，就是import-add-path，这是添加NDK_MODULE_PATH的意思，NDK编译的时候，需要指定的模块路径，当Android.mk中使用**$(call import-module, XXX)，函数引入外部模块时会用到，用来指示该去哪里找这个文件，比如这个cocos2dcpp_shared中，有个$(call import-add-path, $(LOCAL_PATH)/../../../Classes)**，如果我们在Classes/FaceTracker文件下有个Android.mk文件，并且该文件里有个mytrack_static名字的模块，那么我们只需要在当前Android.mk（并非Classes目录下的）文件里的末端加上一句$(call import-module, FaceTracker)，那么它就会在FaceTracker目录(这个目录就是相对Classes目录的)下去找含有mytrack_static模块的Android.mk，并编译。
NOTES:当然为了简洁，我在笔记里就直接用相对cocos2d目录来写FaceTracker目录里的模块，也就是最后一句是$(call import-module, ../Classes/FaceTracker)而不是$(call import-module, FaceTracker)
