CMake:如何在make之后将目录的内容复制到build目录中 [英] CMake: How to copy contents of a directory into build directory after make
问题描述
我有一些配置文件(xml,ini,...)在config目录旁边的源文件。
I've got some config files (xml, ini, ...) in the "config" directory next to the source files. How can I copy all the files in the config directory into the build directory (next to the executable file) each time I make the project?
推荐答案
如何将配置目录中的所有文件复制到构建目录(可执行文件旁边) >
您可以使用 add_custom_command
。
You can use add_custom_command
.
假设你的目标叫做 MyTarget
,你可以:
Say your target is called MyTarget
, you could do:
add_custom_command(TARGET MyTarget PRE_BUILD
COMMAND ${CMAKE_COMMAND} -E copy_directory
${CMAKE_SOURCE_DIR}/config $<TARGET_FILE_DIR:MyTarget>)
每次构建 MyTarget
并将/ config的内容复制到目标exe / lib将要结束的目录中。
This executes every time you build MyTarget
and copies the contents of "/config" into the directory where the target exe/lib will end up.
As Mark Lakata 在下面的评论中指出,用替换
可确保只有在构建成功时才能进行复制。 PRE_BUILD
add_custom_command
中的POST_BUILD
As Mark Lakata points out in a comment below, replacing PRE_BUILD
with POST_BUILD
in the add_custom_command
ensures that copying will only happen if the build succeeds.
