cmaklist流程控制——调试及发布

cmaklist流程控制

目前只会配置-编译调试-打包发布，并且不会workflow控制
后续学习配置-编译调试-测试-打包发布，workflow控制，理解整个流程，目前对流程控制理解也不够。

1.CMake Presets

先于Cmakelist文件，指导项目配置。
参考CMake之Presets编写
**CMAKE_BUILD_TYPE：**指定了编译类型，debug还是release
**CMAKE_INSTALL_PREFIX：**指定了cmakelist中install的前缀路径，类似于cmake -CMAKE_INSTALL_PREFIX
CMakePresets.json

{
    "version": 8,
    "configurePresets": [
        {
            "name": "radar-debug",
            "displayName": "radar-debug",
            "description": "radar-debug",
            "generator": "Unix Makefiles",
            "binaryDir": "${sourceDir}/out/debug/build",
            "cacheVariables": {
                "CMAKE_BUILD_TYPE": "Debug",
                "CMAKE_INSTALL_PREFIX": "${sourceDir}/out/debug/install"
            }
        },
        {
            "name": "radar-release",
            "displayName": "radar-release",
            "description": "radar-release",
            "generator": "Unix Makefiles",
            "binaryDir": "${sourceDir}/out/release/build",
            "cacheVariables": {
                "CMAKE_BUILD_TYPE": "Release",
                "CMAKE_INSTALL_PREFIX": "${sourceDir}/out/release/install"
            }
        }
    ]
}

2.Cmakelist

通过Presets配置的CMAKE_BUILD_TYPE 控制编译，配合add_definitions(-DDEBUG_PRINTF)控制程序表现

cmake_minimum_required(VERSION 3.5.0)
project(radarSerial VERSION 0.1.0 LANGUAGES C CXX)

# Set the default build type to Release if not specified
if(NOT CMAKE_BUILD_TYPE)
    set(CMAKE_BUILD_TYPE Release CACHE STRING "Build type" FORCE)
endif()

# Configure Debug and Release flags
set(CMAKE_CXX_FLAGS_DEBUG "-g -O0")  # Debug信息，关闭优化
set(CMAKE_CXX_FLAGS_RELEASE "-O3")   # 高级优化

if(CMAKE_BUILD_TYPE STREQUAL "Debug")
    add_definitions(-DDEBUG_PRINTF)
    add_definitions(-DDEBUG_ENV)
endif()

find_package(MY_LIBRARY_PATH NAMES CppLinuxSerial PATHS ${CMAKE_CURRENT_SOURCE_DIR}/lib/cmake NO_DEFAULT_PATH REQUIRED)

set(LIB_mqtt3c_PATH /usr/local/lib/)

message(STATUS "CppLinuxSerial_DIR = ${CppLinuxSerial_DIR}")

add_executable(radarSerial main.cpp)

target_include_directories(
    radarSerial 
    PUBLIC 
      "${CMAKE_CURRENT_SOURCE_DIR}/include"
      "${CMAKE_CURRENT_SOURCE_DIR}/include/CppLinuxSerial"
)

target_sources(radarSerial
  PRIVATE 
  ${CMAKE_CURRENT_SOURCE_DIR}/src/comm.cpp
  ${CMAKE_CURRENT_SOURCE_DIR}/src/mqtt.cpp
  ${CMAKE_CURRENT_SOURCE_DIR}/src/cJSON.c)

target_link_libraries(radarSerial CppLinuxSerial::CppLinuxSerial pthread paho-mqtt3c)

install(TARGETS radarSerial RUNTIME DESTINATION bin)
install(FILES
${LIB_mqtt3c_PATH}/libpaho-mqtt3c.so 
${LIB_mqtt3c_PATH}/libpaho-mqtt3c.so.1 
${LIB_mqtt3c_PATH}/libpaho-mqtt3c.so.1.3 
${CMAKE_CURRENT_SOURCE_DIR}/lib/libCppLinuxSerial.so
        DESTINATION lib)
