CMake生成静态库

目录结构

文件内容

• Hello.h

#ifndef MYSHAREDLIB_HELLO_H
#define MYSHAREDLIB_HELLO_H

// 打印 Hello World!
void hello();

// 使用可变模版参数求和
template <typename T>
T sum(T t)
{
    return t;
}
template <typename T, typename ...Types>
T sum(T first, Types ... rest)
{
    return first + sum<T>(rest...);
}

#endif

• Hello.cpp

#include <iostream>
#include "Hello.h"

void hello() {
    std::cout << "Hello, World!" << std::endl;
}

• main.cpp

#include <iostream>
#include "Hello.h"
using std::cout;
using std::endl;

int main() {

    hello();
    cout << "1 + 2 = " << sum(1,2) << endl;
    cout << "1 + 2 + 3 = " << sum(1,2,3) << endl;

    return 0;
}

cmake基本脚本

#cmake版本
cmake_minimum_required(VERSION 3.5)

# 项目名称
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/static)

# 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)

编译

mkdir build
cd build
cmake ..
make
./hell_binary

返回结果

Hello, World!
1 + 2 = 3
1 + 2 + 3 = 6
