如何使用cmake从Visual Studio构建为ia32解决方案 [英] How to build as an ia32 solution from visual studio using cmake
问题描述
我有一个使用 cmake 的模块项目，其配置如下:
I have a module project using cmake with the following configuration:
cmake_minimum_required(VERSION 3.13)
project(app)
set(CMAKE_CXX_STANDARD 11)
add_library(app MODULE src/library.cpp src/library.h)
使用 cmake .. -G"Visual Studio 15 2017 Win64" -DCMAKE_BUILD_TYPE = Release 生成的解决方案之后，我可以找到一个 app.sln 解决方案.
Once solution generated using cmake .. -G "Visual Studio 15 2017 Win64" -DCMAKE_BUILD_TYPE=Release, I can find an app.sln solution.
我使用 Visual Studio 2019 打开它，然后单击 Local Windows Debugger 按钮.我还可以看到一个下拉菜单，其中包含值 x64 和一个项 Configuration Manager .
I open it with Visual Studio 2019 and click on the button Local Windows Debugger. I can see also a drop-down menu containing the value x64 and an item Configuration Manager.
默认情况下为什么没有 ia32 或 x86 选项?我只是无法创建新配置，因为该配置完全不友好.
Why isn't there an ia32 or x86 option by default? I just can't create a new configuration since the configuration is totally non user friendly.
有人想过为目标 32位程序编译库吗?
Anyone has an idea for compile the library for target 32 bits programs?
编辑
我现在使用 cmake进行编译.-G"Visual Studio 16 2019" -DCMAKE_GENERATOR_PLATFORM = x86 -DCMAKE_BUILD_TYPE = Release ，甚至无法加载该项目(因为Visual中缺少一些配置，因为工作室，这就是IDE所说的)
I now compile using cmake .. -G "Visual Studio 16 2019" -DCMAKE_GENERATOR_PLATFORM=x86 -DCMAKE_BUILD_TYPE=Release and the project couldn't be even loaded (cuz of some missing configuration on visual studio, that's what the IDE say)
推荐答案
It appears from the VS 2019 version of the cmake documentation that you should only need to specify:
cmake -G "Visual Studio 16 2019" -A Win32
我将使事情尽可能简单，让 cmake 发挥作用.
and I would keep things as simple as possible and let cmake do its job.
不确定上次评论中什么都没有发生"的意思.当然发生了什么，但是发生的不是您期望或想要的.
Not sure what you mean by "nothing happens" in your last comment. Surely something happened however what happened is not what you expected or wanted.
