工作中 cmakelist 的积累

Demo 记录

• main.cpp

#include 
#include 
include "baz.h"
using namespace std;

int main()
{
  DataBuffer db(10);
  cout << " The value of db is  " << db.data<< endl;
}

• baz.h

class DataBuffer
{
public.
  DataBuffer(int data);

public:
  int data;
};

• baz.cpp

#include 
#include 
include "baz.h"
using namespace std;

DataBuffer::DataBuffer(int data) : data(data)
{
}

• CMakeLists.txt
  注意： 当时一个 bug 是因为 add_executable() 没有把 baz.cpp 添加进去，导致报错 undefined reference o xx

cmake_minimum_required(VERSION 2.8)
