cmake--生成--静态库

一， 目录结构

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

* link:CMakeLists.txt[] - Contains the CMake commands you wish to run
* link:include/static/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静态库
add_library(hello_library STATIC src/Hello.cpp)

# 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
)

# 链接静态库文件
target_link_libraries( hello_binary PRIVATE hello_library)

三，扩展分析

1.  add_library(hello_library STATIC  src/Hello.cpp）将会创建 libhello_library.a 名称的静态库。

2. 域名关键字

* +PRIVATE+ - the directory is added to this target's include directories
* +INTERFACE+ - the directory is added to the include directores for any targets that link this library.
* +PUBLIC+ - As above, it is included int his library and also any targets that link this library.
