例子２：有目录的项目
我现在有个文件夹ProjectDate，有如下文件结构
E:.
│ CMakeLists.txt
│
├─include
│ Date.h
│
└─src
date.cpp
main.cpp
include文件夹下是头文件Date.ｈ
#ifndef DATE_H
#define DATE_H
class Date
{
private:
int m_year;
int m_month;
int m_day;
public:
Date(int year, int month, int day);
void SetDate(int year, int month, int day);
int getYear() { return m_year; }
int getMonth() { return m_month; }
int getDay() { return m_day; }
};
#endif
src文件夹下面是源文件Date.cpp和main.cpp
// Date.cpp
#include "Date.h"
// Date constructor
Date::Date(int year, int month, int day)
{
SetDate(year, month, day);
}
// Date member function
void Date::SetDate(int year, int month, int day)
{
m_month = month;
m_day = day;
m_year = year;
}
// Main.cpp
#include <iostream>
#include "date.h"
int main()
{
Date date(2016,05,05);
std::cout<<"Year:"<<date.getYear()<<" Month:"<<date.getMonth()
<<" day:"<<date.getDay()<<std::endl;
}
CMakeLists.txt内容如下：
cmake_minimum_required(VERSION 3.5.2)
project(directory_test)
#Bring the headers, such as Date.h into the project
include_directories(include)
#Can manually add the sources using the set command as follows:
#set(SOURCES src/mainapp.cpp src/Date.cpp)
#However, the file(GLOB...) allows for wildcard additions:
file(GLOB SOURCES "src/*.cpp")
add_executable(testDate ${SOURCES})
PROJECT指令的语法是：
PROJECT(projectname [CXX] [C] [Java])
用于定义工程名称，并可指定工程支持的语言，默认表示支持所有语言。
这次我们使用cmake命令行，依然建立build文件夹，进入build。首先运行cmake --help看看都有哪些参量可以使用。
> cmake --help
