Debugging C/C++ project in VScode

Hello, I can't debugging my project. Especially, I can't find class "PassiveElement.cpp". I don't know, what is wrong.

launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "C/C++: g++ build and debug active file",

      "command": "code -r ${workspaceFolder}/include ${workspaceFolder}/source",
      "group": "build"
    }
  ]
}

main.cpp

#include <iostream>

int main() {

     std::cout << "SPICE_NOVAK_TEST_VERSION - ZKOUSKA" << std::endl;

    PassiveElement paselem;

    while (true){}//infinity cycle

    return 0;
}
