1. httpserver组件库

   使用/external/httpserver.h-master/src/CMakeLists.txt文件编译的开源库，二次封装接口给到应用层使用。

1.1. 注意事项

1. 编译libhttpsrv时，可能会提示 ragel 工具未安装，需要安装 ragel 工具：

$ sudo apt install ragel

2. 对开源库的CMakeLists.txt文件增加拷贝命令：

message("${PLATFORM_PATH}/cmake-shell/external${SUBMODULE_PATH_OF_IPC_SDK}/httpserver.h-master/src/libhttpsrv.a")
add_custom_command(
    TARGET httpsrv
    POST_BUILD
    COMMAND cp ${PLATFORM_PATH}/cmake-shell${SUBMODULE_PATH_OF_IPC_SDK}/external/httpserver.h-master/src/libhttpsrv.a ${EXTERNAL_LIBS_OUTPUT_PATH}
    WORKING_DIRECTORY ${PLATFORM_PATH}/cmake-shell/
)

3. 取消开源库的CMakeLists.txt文件debug配置，未知会产生什么不良后果；

PUBLIC $<$<CONFIG:DEBUG>:-fsanitize=address -fsanitize=undefined -fno-sanitize-recover=all>
