代码拉取完成，页面将自动刷新
ccORM是最好的ORM对象关系映射底层库，采用最哲学最经典极简的设计，低代码和模块化式的开发，友好的用户体验度。 🚀 支持Linux、windows平台(Mac平台暂时未适配字符串类型检测)。性能超越RTTI和protobuf，是编译期的静态反射。
M_TABLE
多对多查询，索引列，唯一键，以及缓存查询等。

cmake需求：[最好使用vcpkg安装依赖包]
mkdir build
cd build
cmake ..
cmake --build .
如果开关变动，请执行需要的开关选项
cmake -DFastestDev=OFF -DIsDevMode=OFF --build ./
cmake -DFastestDev=OFF -DIsDevMode=ON --build ./
cmake -DFastestDev=ON -DIsDevMode=ON --build ./
然后
cmake --build ./
或者下面的方式对应上面开关选项，这只是示例，注意：请自行修改build_linux.sh文件.通过sh ./build_linux.sh编译
g++ -DFastestDev=0 -DIsDevMode=0 ...线上环境，不会重新建表
g++ -DFastestDev=0 -DIsDevMode=1 ...不重新建表(未改变表结构可用)，开发环境
g++ -DFastestDev=1 -DIsDevMode=1 ...每次会重新建表，开发环境
- Linux: G++ 9.2, Clang++ 9.0
- MacOS: Apple clang version 12.0.0
- Windows: MSVC C++ compiler version 1930.
constexpr -> 小写+大写驼峰分隔，最后一个为大写收尾 => nameBegiN
static 属性 -> _ 开头，后面全小写+下划线分隔 => _name_begin
static 全局变量 -> RES_ 开头，后面全大写+下划线分隔 => RES_NAME_BEGIN
private 属性 -> 小写+大写驼峰分隔， _收尾 => nameBegin_
public 属性 -> 小写+大写驼峰分隔 => nameBegin
参数 -> 小写+下划线分隔 => name_begin
特殊字段 -> _ 开头，中间小写+下划线分隔, _收尾 => _name_begin_
struct或者class -> 大写开头，后面小写+大写驼峰分隔 => NameBegin
宏 或者static constexpr -> 大写+下划线分隔 => NAME_BEGIN
