如何与CMake一起合并多个文件列表？

I have a project built with CMake that needs to copy some resources to the destination folder. Currently I use this code:

我有一个使用CMake构建的项目，需要将一些资源复制到目标文件夹。目前我使用此代码：

file(GLOB files "path/to/files/*")
foreach(file ${files})
    ADD_CUSTOM_COMMAND(
        TARGET MyProject
        POST_BUILD
        COMMAND ${CMAKE_COMMAND} -E copy "${file}" "${CMAKE_BINARY_DIR}/Debug"
    )
endforeach()

Now I want to copy more files from a different folder. So we want to copy files from both path/to/files and path/to/files2 to the same place in the binary folder. One way would be to just duplicate the above code, but it seems unnecessary to duplicate the lengthy custom command.

现在我想从不同的文件夹中复制更多文件。因此，我们希望将文件从path / to / files和path / to / files2复制到二进制文件夹中的相同位置。一种方法是复制上面的代码，但似乎没有必要复制冗长的自定义命令。

Is there an easy way to use file (and possibly the list command as well) to concatenate two GLOB lists?

有没有一种简单的方法来使用文件（也可能是list命令）来连接两个GLOB列表？

2 个解决方案

#1

The file(GLOB ...) command allows for specifying multiple globbing expressions:

文件（GLOB ...）命令允许指定多个globbing表达式：

file(GLOB files "path/to/files/*" "path/to/files2*")

#2

I'd construct a list for each of the patterns and then concatenate the lists:

我将为每个模式构建一个列表，然后连接列表：

file(GLOB files1 "path/to/files1/*")
file(GLOB files2 "path/to/files2/*")
set(files ${files1} ${files2})
