# 15.7 进一步迁移的措施

成功地移植到CMake之后，下一步应该本地化目标和变量的范围：考虑将选项、目标和变量移到更靠近使用和修改它们的地方。避免全局变量，因为它们将按CMake命令顺序进行创建，而这个顺序可能不明显，从而会导致CMake代码变得混乱。强制分离变量范围的一种方法是将较大的项目划分为CMake项目，这些项目使用超构建块组成。从而，可考虑将大型`CMakeLists.txt`文件分割成更小的模块。

接下来的步骤，可以是在其他平台和操作系统上进行配置和编译，以便增强CMake代码的鲁棒性，使其更具可移植性。

最后，将项目迁移到新的构建框架时，开发人员社区也需要去适应。为了帮助您的同事进行培训、文档编制和代码评审。将代码移植到CMake中最困难的部分，可能是改变相关人员的使用习惯。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://chenxiaowei.gitbook.io/cmake-cookbook/15.0-chinese/15.7-chinese.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
