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

问题描述

我正在使用CMake构建一个大型图书馆，我希望用户能够选择性地启用/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.

我如何添加命令行选项到我的CMake构建，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，但是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，你使用选项命令。您可以通过这种方式从命令行设置选项：

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

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

//Command line
cmake -DMyOption=ON MyProjectFolder

请注意，-DMyOption必须在路径之前。

Note that -DMyOption must come before the path.
