CMake COMPONENT关键字详解：组件化安装管理

Understanding the CMake COMPONENT keyword in the install command

Hello there, I recently had a number of questions around the CMake COMPONENT keyword used in the CMake install command and using COMPONENTS in the CMake find_package command.

为了更好的组织 build 产物

实践效果

install command

• 只安装 lib component

  

• 安装所有（NOT CMAKE_INSTALL_COMPONENT 条件成立）

  

cpack

如文章所说，设置 CPACK_COMPONENTS_ALL 即可指定需要打包的组件。

相关资料及理解

@cmake.org: If COMPONENT is not provided a default component “Unspecified” is created. The default component name may be controlled with the CMAKE_INSTALL_DEFAULT_COMPONENT_NAME variable.
