一，目录结构

├── CMakeLists.txt
├── include
│ └── shared
│ └── Hello.h
└── src
├── Hello.cpp
└── main.cpp

* link:CMakeLists.txt[] - Contains the CMake commands you wish to run
* link:include/shared/Hello.h[] - The header file to include
* link:src/Hello.cpp[] - A source file to compile
* link:src/main.cpp[] - The source file with main

二，cmake基本脚本

cmake_minimum_required(VERSION 3.5)

project(hello_library)

# 根据库文件代码生成动态库
add_library(hello_library SHARED src/Hello.cpp)

# 创建动态库别名

add_library(hello_library ALIAS hello_library)

# 包含指定头文件所在的目录
target_include_directories(hello_library PUBLIC ${PROJECT_SOURCE_DIR}/include)

# 创建可执行程序

add_executable(hello_binary
src/main.cpp
)

# 链接动态库文件
target_link_libraries( hello_binary PRIVATE hello::library)

三，扩展分析

1. add_library(hello_library SHARED src/Hello.cpp）将会创建 libhello_library.so 名称的动态库。
