一， 目錄結構
├── 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基本腳本
cmake_minimum_required(VERSION 3.5)
project(hello_library)
# 根據庫文件代碼生成動態庫
add_library(hello_library SHARED src/Hello.cpp)
# 創建動態庫別名
add_library(hello::library ALIAS hello_library)
# 包含指定頭文件所在的目錄
target_include_directories(hello_library PUBLIC ${PROJECT_SOURCE_DIR}/include)
# 創建可執行程序
add_executable(hello_binary
src/main.cpp
)
# 鏈接動態庫文件
target_link_libraries( hello_binary PRIVATE hello::library)
三，擴展分析
1. add_library(hello_library SHARED src/Hello.cpp）將會創建 libhello_library.so 名稱的動態庫。
2. 目標別名
add_library(hello::library ALIAS hello_library)
hello::library是hello_library的別名， 別名允許使用別名來鏈接對應的庫文件。
