对于 CMake 的“安装"命令，COMPONENT 参数可以做什么? [英] For CMake's "install" command, what can the COMPONENT argument do?

问题描述

我不知道 install() 命令意味着，我不理解 CMake 文档.更详细的是什么?

I don't know what the argument COMPONENT of the install() command means, and I don't understand the CMake documentation for this. What is it in more detail?

一个例子是什么?

推荐答案

您可以将安装目标分组到组件中，例如docs"、libs"、runtime"等

You can group installation targets into components, for example, "docs", "libs", "runtime", etc.

add_library(libone libone.c)
add_executable(one main1.c)
install(TARGETS libone one DESTINATION /somedir COMPONENT comp_one)

add_library(libtwo libtwo.c)
add_executable(two main2.c)
install(TARGETS libtwo two DESTINATION /somedir COMPONENT comp_two)

这使得可以运行 cmake -DCOMPONENT=comp_one -P {your_build_dir}/cmake_install.cmake 来仅安装 libone 库和 one 可执行文件.当您发出 make install 时，所有组件都已安装.

This makes it possible to run cmake -DCOMPONENT=comp_one -P {your_build_dir}/cmake_install.cmake to install only the libone library and the one executable. When you issue make install all components are installed.
