如何从命令行设置类型列表的 CMake 变量 [英] How to set CMake variable of type list from command line

问题描述

我正在尝试做这样的事情

I am trying to do something like this

cmake .. -G "Visual Studio 15 2017 Win64" -DCMAKE_CONFIGURATION_TYPES=ReleaseDebug

但是 CMAKE_CONFIGURATION_TYPES 未设置为 list 变量.我也试过

But the CMAKE_CONFIGURATION_TYPES is not set as a list variable. I also tried

cmake .. -G "Visual Studio 15 2017 Win64" -DCMAKE_CONFIGURATION_TYPES="Release Debug"

也没有用.

如何以正确的方式做到这一点?

How to do it the right way?

推荐答案

列表是 CMake 中特殊类型的字符串.当您编写 set(var a b c) 时，它等效于 set(var "a;b;c").这同样适用于您的情况.CMake 将 CMAKE_CONFIGURATION_TYPES 变量解释为一个列表，因此您需要编写 -DCMAKE_CONFIGURATION_TYPES="Release;Debug" 以从命令行正确设置它.

Lists are special type of strings in CMake. When you write set(var a b c) it is equivalent to set(var "a;b;c"). The same applies to your case. CMake interprets CMAKE_CONFIGURATION_TYPES variable as a list, so you need to write -DCMAKE_CONFIGURATION_TYPES="Release;Debug" to properly set it from the command line.
