1. sdsf(single direction single file)

　　1.1  The directory tree

/*./template    |    +--- build    |    +---main.cpp    |    +---CMakeLists.txt */

　　1.2 Sources code

//  main.cpp  #include 
     
       using namespace std;  int main(int argc, char **argv) {      std::cout << "Hello, world!" << std::endl;     return 0; }  //CMakeLists.txt  cmake_minimum_required(VERSION 2.6) //------The minimum version required---//  project(template) //------The project information-----//  add_executable(template main.cpp) //-----Build Target------//  install(TARGETS template RUNTIME DESTINATION bin)
     

　　1.3 Compile All

1 cd build2 cmake .. 3 make

2. Single direct Multi- files

    2.1 The directory tree

/* ./template    |    +--- build/    |    +---main.cpp    |    +---a.cpp    |    +---CMakeLists.txt*/

　　2.2 Sources Code

//  main.cpp  #include 
     
      #include "a.h"using namespace std;int main(int argc, char **argv) {       display();        std::cout << "Hello, world!" << std::endl;    return 0;}// a.cpp#include "a.h"using namespace std;void display(void){  cout << "I'm in a.cpp"<< endl;  }// a.h#ifndef A_H_#define A_H_#include 
      
       void display(void);#endif //CMakeLists.txt  cmake_minimum_required(VERSION 2.6) //------The minimum version required---//  project(template) //------The project information-----//  add_executable(template main.cpp a.cpp) //-----Build Target------//  install(TARGETS template RUNTIME DESTINATION bin)
      
     

 only add a.cpp in add_executable ,and there is a accepted way----used command  aux_source_directory 

// CMakeListscmake_minimum_required(VERSION 2.6)project(template)aux_source_directory(./  allfiles)   // The current diradd_executable(template ${allfiles})install(TARGETS template RUNTIME DESTINATION bin)
