After that I will create two different folders called source and build in this directory seperately:
I will create a new file called CMakeLists.txt in Source directory. We must do it because we set how CMake should compile the project from the CMakeLists.txt file.
I typed cmake -G "MinGW Makefiles" ../Source command like in above. After this command, CMake will generate Makefiles into the Build directory. If you notice I used MinGW Makefiles. This is a generator that CMake supports one of the generators. I use Windows, therefore I used MinGW in my computer. If you use Ubuntu distro you can use Unix Makefiles as generator for CMake.
In the command, I specified the path of Source to reach CMakeLists.txt and we created Makefile script for our project via -G option.
I got a warning about usage of CMakeLists.txt, because I didn't add project() command in CMakeLists.txt. I'll mention it here shortly.
Let's open Build directory and we can see what CMake generated:
I opened CMakeLists.txt and I typed this lines:
cmake_minimum_required(VERSION 3.22.0)
project(sample)
So I want to build an example program. I will type a C++ program as an example:
#include <iostream>
int main()
{
std::cout << "Hello World!" << std::endl;
return 0;
}
Open CMakeLists.txt again and let's add executable as an output program with this command:
cmake_minimum_required(VERSION 3.22.0)
project(sample)
add_executable(${PROJECT_NAME} main.cpp)
That's fine, but I want to the create with different way now like in the below:
Now we have to build target with make command. At first I need to go inside of Build directory:
We built target successfully. Now let's run it:
