CMake：管理源文件列表 [英] CMake: Managing a list of source files

问题描述

我现在遇到的问题是，我只是想通过抓取一切，并删除我不需要的几个奇数和结束来管理我的源文件列表。我希望Cmake为此提供了很好的内置工具。

The problem I'm having at the moment is that I simply wish to manage my list of source files by grabbing everything and removing the few odds and ends that I do not need. I was hoping that Cmake provided nice built-in tools for this.

所以我可以从：

file(GLOB A "Application/*.cpp")

我想要创建另一个要删除的文件列表，我想告诉CMake：从列表B中删除列表B中的项目。

I feel like I want to create another list of files to be removed and I want to tell CMake: Remove from list A items that are in list B.

如果这是Python我可能会做类似下面的事情：

If this were Python I might do something like:

C = [f for f in A if f not in B]

我可能已经拧了那个语法，但我想知道是否有内置的支持管理这些文件列表更优雅的方式？

I may have screwed that syntax up but I'm wondering if there is built-in support for managing these lists of files in a more elegant way?

即使我可以做我的Python示例，A是绝对路径列表，因此构建B是笨重的。

Even if I could do something like my Python example, A is list of absolute paths so constructing B is clunky.

为什么绝对路径？

推荐答案

如果你喜欢Python，你可以生成你的包含 execute_process 的源文件列表。还可以使用列表。

If you like Python, you can generate your list of source files with execute_process. There is also possiblity to work with lists.

但我建议您硬编码您的源文件列表。
文件命令文档说明：

But I would recommend you to "hardcode" your list of source files. File command documentation states:

我们不建议使用GLOB从源代码树中收集源文件列表。如果在添加或删除源时没有CMakeLists.txt文件更改，那么生成的构建系统无法知道何时请求CMake重新生成。

We do not recommend using GLOB to collect a list of source files from your source tree. If no CMakeLists.txt file changes when a source is added or removed then the generated build system cannot know when to ask CMake to regenerate.
