一、同时拥有两个工程项目时的配置（APP IAP）方便git等工具的管理
1.1、目录结构如下：
|-Power_prj
|-CMakelists.txt
| |-Power_APP
| | |-src
| | |-include
| | |-main.c
| | |-CMakelists.txt
| |-Power_IAP
| | |-src
| | |-include
| | |-main.c
| | |-CMakelists.txt1.2、CMakelists.txt说明：
Power_prj下的CMakelists.txt里面包含两个项目即可
cmake_minimum_required(VERSION 3.14.0)
project(hc32f072_prj)
# 添加子目录，这会触发子目录中的CMakeLists.txt文件的执行
add_subdirectory(Power_APP/)
add_subdirectory(Power_IAP/)
对应Power_APP与Poer_IAP中的CMakelists.txt按实际需求编写，路径生成文件通过set(CUSTOM_BIN_DIR "${CMAKE_BINARY_DIR}/Power_IAP") 配置。另头文件的使用需使用target_include_directories进行路径的加载，否则源文件中调用时需要指定绝对路径，示例如下（Power_IAP）：
cmake_minimum_required(VERSION 3.14.0)
set(CMAKE_SYSTEM_NAME Generic)
set(CMAKE_SYSTEM_PROCESSOR arm)
set(CUSTOM_BIN_DIR "${CMAKE_BINARY_DIR}/Power_IAP")
project(hc32f072_Iap)

# 全局宏定义
add_definitions(
-D__STACK_SIZE=8*1024
-D__HEAP_SIZE=32*1024
-DHC32F448
-DUSE_DDL_DRIVER
)
add_compile_options(
-mno-unaligned-access
-fgnu89-inline

二、cmake使用命令暂记
2.1、Windows下使用cmake清除build下的文件：
cmake --build ./ --target clean
