Cmake提供了install关键字，用于对应make install功能。安装的文件包括可执行文件、静态库、动态库、文件、目录、脚本文件。

install(TARGETS <target>... [...])
    install({ FILES | PROGRAMS} <file>... [...])
    install(DIRECTORY <dir>... [...])
    install(SCRIPT <file> [...])
    install(CODE <code> [...])
    install(EXPORT <export-name> [...])

CONFIGURATIONS：Debug或Release
    ARCHIVE			：安装文件name中的所有静态库类型文件，指定后续的安装路径
    LIBRARY			：安装文件name中的所有动态库类型文件，指定后续的安装路径
    RUNTIME			：安装文件name中的所有可执行文件，指定后续的安装路径
    PRIVATE_HEADER	：私有头文件安装
    PUBLIC_HEADER	：公有头文件安装

若路径尚未指定，则会安装到系统默认对应的路径中，例如库文件会默认安装到/usr/local/lib/，但在使用make install时要附带sudo属性，否则会提示没有权限

to "/usr/local/lib/libtest_lib.so.1.2.3.4": Permission denied.

# 安装库文件：TARGETS #

采用TARGETS安装  
安装路径可自定义

install(TARGETS ${SOURCE_LIB}
            CONFIGURATIONS ${CMAKE_BUILD_TYPE} # Debug 或 Release
            ARCHIVE DESTINATION ${PROJECT_SOURCE_DIR}/target/${CMAKE_BUILD_TYPE}/staticLib  #静态库安装路径
            LIBRARY DESTINATION ${PROJECT_SOURCE_DIR}/target/${CMAKE_BUILD_TYPE}/sharedLib) #动态库安装路径

# 安装可执行程序：TARGETS #

采用TARGETS安装  
安装路径可自定义

install(TARGETS ${PROJECT_APP}
         CONFIGURATIONS ${CMAKE_BUILD_TYPE}
    		RUNTIME DESTINATION ${PROJECT_SOURCE_DIR}/target/${CMAKE_BUILD_TYPE})

# 安装文件夹：DIRECTORY #

采用DIRECTORY安装，对应的文件夹以及里面的文件会复制到安装的指定路径中  
安装路径可自定义

install(DIRECTORY ${PROJECT_SOURCE_DIR}/file
            DESTINATION ${PROJECT_SOURCE_DIR}/target)

# 安装文件：FILES或PROGRAMS #

FILES为普通文件，PROGRAMS为非目标程序，例如shell脚本。  
官网有详细说明：

> https://cmake.org/cmake/help/v3.15/command/install.html?highlight=install

The PROGRAMS form is identical to the FILES form except that the default permissions for the installed file also include OWNER_EXECUTE, GROUP_EXECUTE, and WORLD_EXECUTE. This form is intended to install programs that are not targets, such as shell scripts. Use the TARGETS form to install targets built within the project.

PERMISSIONS：后面跟着赋予的权限，有效的权限官网有详细说明

PERMISSIONS
    Specify permissions for installed files. Valid permissions are OWNER_READ, OWNER_WRITE, OWNER_EXECUTE, GROUP_READ, GROUP_WRITE, GROUP_EXECUTE, WORLD_READ, WORLD_WRITE, WORLD_EXECUTE, SETUID, and SETGID. Permissions that do not make sense on certain platforms are ignored on those platforms.

安装路径可自定义

# 安装文件，可读可写
    install(FILES ${PROJECT_SOURCE_DIR}/testfile.txt
    		DESTINATION ${PROJECT_SOURCE_DIR}/target
    		PERMISSIONS OWNER_READ OWNER_WRITE)
    
    # 安装shell脚本，只读
    install(PROGRAMS ${PROJECT_SOURCE_DIR}/testsh.sh
    		DESTINATION ${PROJECT_SOURCE_DIR}/target
    		PERMISSIONS OWNER_READ OWNER_EXECUTE)
