I dont know how to change the compiler to G this is the cmake

cmake_minimum_required(VERSION 3.0)
set(CMAKE_C_COMPILER "gcc")
set(CMAKE_CXX_COMPILER "g  ")
project(HelLo)
add_executable(Hello main.cpp hello.cpp)

cmake -G "Unix Makefiles" ..

First, make sure you've installed gcc/g under Windows (either CygWin or MinGW). Remove the set commands from your CMakelists.txt. Then in a CygWin/MinGW shell use the following command to generate the Makefile:

CC=gcc CXX=c   cmake ..
