基于STM32的CMAKE模板
这是一个基于STM32单片机的模板； 示例中的单片机是STM32H743IIT6，调试器使用JlinkOB； 其中的各个参数可以参考使用STM32CubeMX生成的基于makefile的模板，且后续仍然可以使用STM32CubeMX进行底层代码的构建； 如果需要进行调试，可以先启动J-Link GDB Server，然后使用VSCode进行调试或者直接使用命令行进行调试； # CMAKE_SYSTEM_NAME: 即你目标机target所在的操作系统名称，比如ARM或者Linux你就需要写"Linux"; # 如果Windows平台你就写"Windows",如果你的嵌入式平台没有相关OS你即需要写成"Generic"; # 只有当CMAKE_SYSTEM_NAME这个变量被设置了，CMake才认为此时正在交叉编译; # 它会额外设置一个变量CMAKE_CROSSCOMPILING为TRUE; set(CMAKE_SYSTEM_NAME Generic) # CMAKE_SYSTEM_NAME和CMAKE_SYSTEM_PROCESSOR是交叉编译的时候必须指定的两个参数; # 如果在cmake命令行定义了CMAKE_SYSTEM_NAME,就必须也定义CMAKE_SYSTEM_PROCESSOR; set(CMAKE_SYSTEM_PROCESSOR cortex-m7) #cmake最低版本 cmake_minimum_required(VERSION 3.1.0) #编译工具 set(CROSS_COMPILE_PREFIX arm-none-eabi) # 顾名思义，即C语言编译器，这里可以将变量设置成完整路径或者文档名; # 设置成完整路径有一个好处就是CMake会去这个路径下去寻找编译相关的其他工具; # 比如linker,binutils等，如果你写的文档名带有arm-elf等等前缀; # CMake会识别到并且去寻找相关的交叉编译器; set(CMAKE_C_COMPILER ${CROSS_COMPILE_PREFIX}-gcc) set(CMAKE_CXX_COMPILER ${CROSS_COMPILE_PREFIX}-g++) set(CMAKE_ASM_COMPILER ${CROSS_COMPILE_PREFIX}-gcc) set(CMAKE_OBJCOPY ${CROSS_COMPILE_PREFIX}-objcopy) set(CMAKE_OBJDUMP ${CROSS_COMPILE_PREFIX}-objdump) set(CMAKE_SIZE ${CROSS_COMPILE_PREFIX}-size) #

search for program/library/include in the build host directories # 1、CMAKE_FIND_ROOT_PATH_MODE_PROGRAM: 对FIND_PROGRAM()起作用， # 有三种取值，NEVER,ONLY,BOTH, # 第一个表示不在你CMAKE_FIND_ROOT_PATH下进行查找， # 第二个表示只在这个路径下查找， # 第三个表示先查找这个路径，再查找全局路径， # 对于这个变量来说，一般都是调用宿主机的程序，所以一般都设置成NEVER # # 2、CMAKE_FIND_ROOT_PATH_MODE_LIBRARY: 对FIND_LIBRARY()起作用， # 表示在链接的时候的库的相关选项，因此这里需要设置成ONLY来保证我们的库是在交叉环境中找的. # # 3、CMAKE_FIND_ROOT_PATH_MODE_INCLUDE: 对FIND_PATH()和FIND_FILE()起作用， # 一般来说也是ONLY,如果你想改变，一般也是在相关的FIND命令中增加option来改变局部设置 # 有NO_CMAKE_FIND_ROOT_PATH,ONLY_CMAKE_FIND_ROOT_PATH,BOTH_CMAKE_FIND_ROOT_PATH set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY) set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY) #工程名称 #
