CMake - change current directory ( for example: project/build ) from CMakeLists.txt?
提问by vir2al
I'm building project with CMake. While configuration and building I'm in directory project/build . How can I change the directory in CMake and execute a bash script from another directory.
我正在用 CMake 构建项目。在配置和构建时，我在目录 project/build 中。如何更改 CMake 中的目录并从另一个目录执行 bash 脚本。
execute_process( COMMAND cd ../ ) - doesn't work. When I execute this CMake doesn't change its directory and I'm again in project/build.
execute_process( COMMAND cd ../ ) - 不起作用。当我执行这个 CMake 不会改变它的目录，我又在项目/构建中。

The WORKING_DIRECTORYdirective of the execute_processcommand lets you directly specify the directory the script is to be run from.
该WORKING_DIRECTORY命令的execute_process指令允许您直接指定要运行脚本的目录。
execute_process(COMMAND ${CMAKE_SOURCE_DIR}/script.sh args
WORKING_DIRECTORY ${CMAKE_SOURCE_DIR})

With ${CMAKE_SOURCE_DIR}you get the source path. Executing a binary from the source directory would be
随着${CMAKE_SOURCE_DIR}你得到源路径。从源目录执行二进制文件将是
execute_process(${CMAKE_SOURCE_DIR}/bin/myscript.sh)
If you need to handle files from the build directory you have to add them like
如果您需要处理构建目录中的文件，则必须像这样添加它们
execute_process(${CMAKE_SOURCE_DIR}/bin/myscript.sh ${CMAKE_CURRENT_BINARY_DIR}/input.txt)
Overall the variables CMAKE_SOURCE_DIR, CMAKE_CURRENT_SOURCE_DIR, CMAKE_BINARY_DIR, and CMAKE_CURRENT_BINARY_DIRare very helpful. You can find a more complete list at http://www.cmake.org/Wiki/CMake_Useful_Variables
总的来说，变量CMAKE_SOURCE_DIR、CMAKE_CURRENT_SOURCE_DIR、CMAKE_BINARY_DIR和CMAKE_CURRENT_BINARY_DIR非常有用。您可以在http://www.cmake.org/Wiki/CMake_Useful_Variables找到更完整的列表
