主要涉及三个命令：execute_process、add_custom_target和add_custom_c

实现背景在定位问题时，固件无法获取当前设备中版本的详细信息，无法准确获取版本具体内容输出效果实现方式以下是基于Cmake的语法实现在CMake中获取git信息，可以通过execute_process命令运行

#getgithashmacro(get_git_hash_git_hash)find_package(GitQUIET)if(GIT_FOUND)execute_process(COMMAND${GIT_EXECUTABLE

#项目名称project(example)#最低的cmake版本cmake_minimum_required(VERSION2.8)#执行Shell命令，抑制message警告#execute_process

execute_process执行一个或更多个子进程。运行一条或多条命令，使得前一条命令的标准输出以管道的方式成为下一条命令的标准输入。所有进程公用一个单独的标准错误管道。

我的报错如下：{CMakeErrorat/opt/ros/melodic/share/catkin/cmake/safe_execute_process.cmake:11(message):execute_process

在构建target之前跑shell脚本execute_process(COMMANDshgen_c_source.sh${CMAKE_BINARY_DIR}WORKING_DIRECTORY${CMAKE_SOURCE_DIR

比如把文件grpc-gitclone.cmake：execute_process(COMMAND${CMAKE_COMMAND}-Eremove_directory"E:/install/tensorflow

execute_process(COMMANDgitlog-1--format=%H//git命令WORKING_DIRECTORY${PROJECT_

在cmake文件里定义如下:execute_process(COMMANDgitlog-1--format="%H"WORK

:11(message):CMakeErrorat/opt/ros/kinetic/share/catkin/cmake/safe_execute_process.cmake:11(message):execute_process

按照官网安装，遇到问题CMakeErrorat/opt/ros/kinetic/share/catkin/cmake/safe_execute_process.cmake:11(message):execute_process

catkin_make后出现:CMakeErrorat/opt/ros/indigo/share/catkin/cmake/safe_execute_process.cmake:11(message):execute_process

最后用的file指令,write会替换自生成#ADD_DEFINITIONS(-DSVNVERS=4)#ADD_DEFINITIONS(-DSVNVERS=\"ssss\")EXECUTE_PROCESS

摘要：execute_process我在cmake编译后想执行一些特定的shell命令（执行、lcov收集代码覆盖报告等），我又不想写到XX.sh的shell脚本中，如何直接通过CMake执行shell

用途：执行一个或多个子进程  execute_process(COMMAND[args1...]]                 

新增内容： 这个命令，可以在makeinstall时执行期望的命令install(CODE"execute_process(COMMANDls${CMAKE_INSTALL_PREFIX}/bin/foo
