向 CMake 添加命令行选项 [英] Adding command line options to CMake

问题描述

我正在使用 CMake 构建一个大型库，我希望用户能够有选择地启用/禁用我的构建过程的某些部分.

I'm building a large library using CMake, and I would like users to be able to selectively enable/disable certain parts of my build process.

如何将命令行选项添加到我的 CMake 构建中，例如以便用户可以输入类似 cmake --build-partone --nobuild-parttwo --dothis=true --dothat=false ..?

How can I add command-line options to my CMake build, e.g. so that users may type something like cmake --build-partone --nobuild-parttwo --dothis=true --dothat=false ..?

显然 OPTION 关键字将创建可以从 CMake GUI 设置的变量，但我不知道如何从命令行执行此操作.

Apparently the OPTION keyword will create variables that can be set from the CMake GUI, but I can't figure out how to do this from the command line.

推荐答案

是的，您应该使用 option 命令.您可以通过以下方式从命令行设置选项:

Yeah, you should use the option command. You can set options from the command line this way:

//CMakeLists.txt
option(MyOption "MyOption" OFF)

//Command line
cmake -DMyOption=ON MyProjectFolder

注意 -DMyOption 必须在路径之前.

Note that -DMyOption must come before the path.
