cmake下使用boost，以shared_ptr和make_shared舉例

Cmake文件配置

首先需要在CmakeLists.txt文件中加入下面這段
記得“YourExeName和 YourSourceCodeName”這兩個部分需要替換成自己的源文件名字和自己想生成的目標文件名字

find_package(Boost)
if(Boost_FOUND)
    include_directories(${Boost_INCLUDE_DIRS})
    add_executable(YourExeName YourSourceCodeName.cpp)
    target_link_libraries(main ${Boost_LIBRARIES})
endif()

boost shared_ptr和make_shared舉例

#include <iostream>
#include <boost/shared_ptr.hpp>
#include <boost/make_shared.hpp>
int main() {
    boost::shared_ptr<int> ptr = boost::make_shared<int>(1);
    std::cout << *ptr << std::endl;
    return 0;
}
