android NDK 編譯其它目錄的c++文件

     最近在做圖形識別算法，語言用的c++，開源庫用的opencv。需要移植到android。經過幾天實踐，終於成功，現記錄下來，希望對別人有幫助

     其它的android.mk文件，都是編譯本目錄下的文件。而本人做的圖形算法，要在多個平臺下編譯，最開始是做的 windows下版本，vs2015的項目，故不將c++文件和目錄拷貝到jni目錄下，而是直接將android.mk裏指定到vs所在目錄

我的android.mk內容如下

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
