Compile cpp file

when conflict happen

like cmakecache doesnt match: remove build file , start again rm -rf build

add_executable how to include all c++ file:

1. file(GLOB SOURCES "*.cpp") searching for current folder, adding all c++ file into SOURCES variable and then add_executable(vulkanTest ${SOURCES}). Therefore collect all c++ under current directory but if add more c++ files later, need to cmake again
2. manually add all c++ files name here

extra: Fast simple compile cpp

in this case can use g++ g++ test.cpp -o test && ./test

• -o test :specify the output executable name is test
• && and
• ./test run the compiled file

Simple Start

#include <iostream>
using namespace std;
int main() {

  cout << "Hello, World!" << endl;
  return 0;
}

Multiple entry

void entry1(){
  std::cout<<"entry point"<<std::endl;
}

int main() {
  entry1();
  return 0;
}
