# TODO

# NOTE
- HDU OJ 定义了 ONLINE_JUDGE 宏
- CMakeLists.txt
    - 设置宏 LOCAL_JUDGE, 用于区分本地和ONLINE
    - 设置 CMAKE_EXPORT_COMPILE_COMMANDS 选项, 用于导出编译命令

# Build
```sh
cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=YES -DCMAKE_BUILD_TYPE=Debug -S ~/OJ -B ~/OJ/build -DMAIN:STRING=kmp.cpp
ln -s build/compile_commands.json
```
