cmake命令行生成32位和64位项目 - mohist - 博客园
概述
- 本文演示环境: win10 + VS2017
1.指定变量值
咱们常用命令【cmake ..】在build目录下配置生成项目和解决方案。 其实,这个命令还有其他用法。
指定CMakeLists.txt中的变量值。比如 , fmt 库 的CMakeLists.txt中有一个变量 【BUILD_SHARED_LIBS】,可以在命令行指定其值:
cmake -DBUILD_SHARED_LIBS=TRUE ..
对比可知,多了中间指定变量的命令, 其他没有变化。
2.指定编译器版本
使用命令: cmake -G 可知当前cmake支持的编译器
Generators
Visual Studio 17 2022 = Generates Visual Studio 2022 project files.
Use -A option to specify architecture.
* Visual Studio 16 2019 = Generates Visual Studio 2019 project files.
Use -A option to specify architecture.
Visual Studio 15 2017 [arch] = Generates Visual Studio 2017 project files.
Optional [arch] can be "Win64" or "ARM".
Visual Studio 14 2015 [arch] = Generates Visual Studio 2015 project files.
Optional [arch] can be "Win64" or "ARM".
Visual Studio 12 2013 [arch] = Generates Visual Studio 2013 project files.
Optional [arch] can be "Win64" or "ARM".

Optional [arch] can be "Win64" or "ARM".
Visual Studio 10 2010 [arch] = Deprecated. Generates Visual Studio 2010
project files. Optional [arch] can be
"Win64" or "IA64".

Optional [arch] can be "Win64" or "IA64".
Borland Makefiles = Generates Borland makefiles.
NMake Makefiles = Generates NMake makefiles.
NMake Makefiles JOM = Generates JOM makefiles.
MSYS Makefiles = Generates MSYS makefiles.
MinGW Makefiles = Generates a make file for use with
mingw32-make.
Green Hills MULTI = Generates Green Hills MULTI files
(experimental, work-in-progress).
Unix Makefiles = Generates standard UNIX makefiles.
Ninja = Generates build.ninja files.
Ninja Multi-Config = Generates build-<Config>.ninja files.
Watcom WMake = Generates Watcom WMake makefiles.
CodeBlocks - MinGW Makefiles = Generates CodeBlocks project files.
CodeBlocks - NMake Makefiles = Generates CodeBlocks project files.
CodeBlocks - NMake Makefiles JOM
= Generates CodeBlocks project files.
CodeBlocks - Ninja = Generates CodeBlocks project files.
CodeBlocks - Unix Makefiles = Generates CodeBlocks project files.
CodeLite - MinGW Makefiles = Generates CodeLite project files.
CodeLite - NMake Makefiles = Generates CodeLite project files.
CodeLite - Ninja = Generates CodeLite project files.
CodeLite - Unix Makefiles = Generates CodeLite project files.
Eclipse CDT4 - NMake Makefiles
= Generates Eclipse CDT 4.0 project files.
Eclipse CDT4 - MinGW Makefiles
= Generates Eclipse CDT 4.0 project files.
Eclipse CDT4 - Ninja = Generates Eclipse CDT 4.0 project files.
Eclipse CDT4 - Unix Makefiles= Generates Eclipse CDT 4.0 project files.
Kate - MinGW Makefiles = Generates Kate project files.
Kate - NMake Makefiles = Generates Kate project files.
Kate - Ninja = Generates Kate project files.
Kate - Unix Makefiles = Generates Kate project files.
Sublime Text 2 - MinGW Makefiles
= Generates Sublime Text 2 project files.
Sublime Text 2 - NMake Makefiles
= Generates Sublime Text 2 project files.
Sublime Text 2 - Ninja = Generates Sublime Text 2 project files.
Sublime Text 2 - Unix Makefiles
= Generates Sublime Text 2 project files.
前面带星号*表示当前安装的编译器。
给cmake 传递参数 -G 指定编译器的例子如下(指定VS2017为例):
cmake -G "Visual Studio 15 2017 " ..
该命令将默认生成32位程序
注意: “..”前面有空格
【扩展】Linux/Unix cmake指定clang为默认编译器
3.指定指定生成64位的配置命令
上面显示Vs的版本已经说明了参数格式: Visual Studio 9 2008 [arch] 。 这里的 [arch] 就是需要指定的平台目标。可以是”Win64” or “ARM”。
还是以VS2017为例,编译生成64位,命令如下:
cmake -G "Visual Studio 15 2017 Win64" ..
对比 【2】中的命令多了 “Win64”
4.指定目录下的CMakeLists.txt
习惯上,我更喜欢在和top目录下新建build 目录, 将输出的文件放到这里。【cmake ..】 命令中的【..】其实就是指定 top目录下的CMakeLists.txt文件。
原型:
cmake to/path/cmake_lists_txt_dir
其中【 to/path/cmake_lists_txt_dir 】则指向的是CMakeLists.txt所在目录。
