cocos2dx 3.9 升级 3.17

1.更改环境变量，使用cocos2dx3.17

2.想新工程中添加三方库

3.跟新工程头文件引用

4.openssl冲突修改三方库的函数引用中cocos自带的库

5.添加android app/android.mk 头文件引用，注意相对路径

6.android编译错误：

cocos compile --compile-script 0 -m release -p android

ndk低版本中sys/atomics.h被stdatomics.h替换，使用其中函数重写:

#include 
int atomicDecrement(volatile int* t) {
    __sync_fetch_and_sub(t, 1);
    return *t;
}
int atomicIncrement(volatile int* t) {
    __sync_fetch_and_add(t, 1);
    return *t;
}
#elif (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32 || CC_TARGET_PLATFORM == CC_PLATFORM_WP8)

7.

android studio 3.3

编译模式：release
使用 Android Studio 工程：/Users/admin/code/client/project_wly2_lua_client/frameworks/runtime-src/proj.android
配置文件 '/Users/admin/code/client/project_wly2_lua_client/frameworks/runtime-src/proj.android/build-cfg.json' 不存在或者已损坏。

修改.cocos_project文件
