结构说明

---

本章节主要目的是将头文件的代码组织编译成接口库（接口目标）
app目录存放应用层代码
cmake存放cmake include的代码
main中存放主函数代码

CMakeLists.txt

CMakeLits.txt最外层调用cmake/utils.cmake

最外层的CMakeLists

cmake_minimum_required (VERSION 3.5)
include (cmake/utils.cmake)
project(subprojects)

# Add sub directories
# 定义子目录src，用以递归的调用src中的MakeLists.txt
add_subdirectory(app)

set(zc_lib
    lib::app1
)

zc_add_executable(test_main "main/main.c" "${zc_lib}")
