 2 同文件夹多个编译

CMakeLists.txt

cmake_minimum_required(VERSION 2.6)
project(tcp)

#自动连接模式

#1将文件夹下全部文件链接到 src
#aux_source_directory(. src)
#将src里面的所有文件链接用于生成可执行文件
#add_executable(project1 ${src})      

#手动添加模式
#1测试-生成可执行文件main
add_executable(main src/main.cpp)

add_executable(client src/client.cpp)

add_executable(Server src/Server.cpp)

add_executable(http_client src/http_client.cpp)

 #设置可执行文件的输出目录
SET(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)

3 分文件夹间接编译

CMakeLists.txt

#1工程名字
PROJECT(main)
#2版本要求
CMAKE_MINIMUM_REQUIRED(VERSION 2.6)

#3-1该命令会把参数 <.当前文件夹> 中所有的源文件名称赋值给参数 <DIR_SRCS>
AUX_SOURCE_DIRECTORY(. DIR_SRCS)
#3-2包含src文件夹下的内容,会自动到该文件夹下寻找新的cmake
ADD_SUBDIRECTORY( src )

#0 指示变量 DIR_SRCS 中的源文件需要编译 成一个名称为 main 的可执行文件。
ADD_EXECUTABLE(main ${DIR_SRCS})

#-1 链接库
TARGET_LINK_LIBRARIES( main Test )

 main.cpp

#include <iostream>
using namespace std;
#include "src/print_drc.cpp"
#include "src/print_src.cpp"

int main()
{

    print_drc();
    print_src();

    cout<<"hello world"<<endl;
    return 1;
}

CMakeLists.txt

#3-1该命令会把参数 <.当前文件夹> 中所有的源文件名称赋值给参数 <DIR_TEST1_SRCS>
AUX_SOURCE_DIRECTORY(. DIR_TEST1_SRCS)

#0 指示变量 DIR_SRCS 中的源文件需要编译 成一个名称为 main 的可执行文件。
#ADD_EXECUTABLE(main ${DIR_SRCS})
#0 指示变量 DIR_TEST1_SRCS 中的源文件需要编译 成一个名称为 main 的库。
ADD_LIBRARY ( Test ${DIR_TEST1_SRCS})

 print_drc.cpp

#include <iostream>

using namespace std;

int print_drc()
{
    cout<<"1 这是来自直接目录下的测试！"<<endl;
    return 1;
}

print_src.cpp

#include <iostream>

using namespace std;

int print_src()
{
    cout<<" 2 这是来自src下的测试！"<<endl;
    return 1;
}
