* 1. 生成lump，并且添加到工程

3. 将libil2cpp目录复制到 Library/. 删除旧的. search paths里修改 libil2cpp/include为libil2cpp
|
3. Libraries/bdwgc/include -> Libraries/external/bdwgc/include
|
4. 将external目录复制到 Library/external。删除旧目录
|
5. 将Library/external/baselib/Platforms/OSX改名为 IOS 全大写
|
6. 将 external/zlib下c 文件添加到工程
|
7. 移除libil2cpp.a
|
8. Include path add libil2cpp/os/ClassLibraryPAL/brotli/include
|
9. add external/xxHash
|
10. add "#include <stdio.h>" to Classes/Prefix.pch
