#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

CMake Error at CMakeLists.txt:2 (project):
  The CMAKE_C_COMPILER:

    C:/cygwin64/bin/gcc.exe

  is not a full path and was not found in the PATH.

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.
