问题标签 [add-custom-target]

我有一个公司内部工具，它使用以下模式在每个命令行中获取多个文件

要将此工具添加到我的 CMake 构建中，我一直在使用 add_custom_target 命令，如下所示

只要 FILES 仅扩展为单个文件，此方法就可以正常工作，但是当我传入多个文件时，该命令开始仅产生垃圾输出。在检查 CMake 生成的 build.ninja 文件后，我发现 custom_target 命令被转换为一个调用，其中参数后跟这样的反斜杠

我怀疑这就是这不起作用的原因。

现在为什么 F. CMake 会这样做，我该如何摆脱这种行为？

/edit
在将 FILES 字符串传递给 add_custom_target 之前打印它我看不到那些反斜杠...

好的，我知道了。构建一个新列表并在 foreach 循环中附加 -i 和文件是有效的。

我正在尝试创建一个 cmake (3.22) 函数，该函数创建一个cppclean为我在参数中提供的目标调用的目标

但是我不处理错误：

没有这样的文件或目录：'--include-path ... --include-path ... --include-path ...'

当我查看创建的 make 文件时，我确实看到了扩展生成器表达式周围的引号，这可能是错误的。

如果我删除生成器表达式周围的引号，它会给出不同的错误：

无法创建/home/foo/src：是目录

并且make文件显示JOIN表达式没有展开。

如何解决这个问题？

I have a python script, which generates some files for me, and in my script, I have an argument --outputdir to specify the location of output files. I want to run this script to generate these files and install them later. I used

So output files are generated under ${CMAKE_CURRENT_BINARY_DIR}, and I can install them later.

but above code did not work, because I have to use a TARGET or OUTPUT from the error message. So if I use a dummy one:

This just worked and I can see files are generated under ${CMAKE_CURRENT_BINARY_DIR}. I believe if I use something like:

this should also work. My question is why do I need a dummy target anyway? Actually just with COMMAND I can run my script and with args I can specify where the output files are generated, then with some install command I can install files around. So Am I correct to use a dummy target in this case and do I have to use a it? Note generateFiles.py are not changed during the build process and will generate the same files every time. Thanks, i am new to CMake.
