How to Set Up SDL2 using Eclipse ubuntu - c++

Question

I've been trying to get SDL2 working with Eclipse on Ubuntu.
I have tried following this, this, and this but I just cannot get it working.
How can I get SDL2 working with Eclipse and have everything properly linked together?
EDIT:
When ever I compile the program it comes back saying that SDL.h is missing or there is no such directory, even though i can see SDL in the includes from the project list.
When compiling i have tried using:
gcc SDLTest.cpp
g++ SDLTest.cpp
gcc -o test SDLTest.cpp `sdl-config --cflags --libs`
I'm unsure of the difference between using GCC or G++, and i got the third compile from here.
I've added the SDL include folder to the project but still nothing
Image Project Explorer and Code
GCC C++ Linker Libraries
#include <SDL2/SDL.h>
#include <stdio.h>
int main(int argc, char* argv[])
{
SDL_Window *window;
SDL_Init(SDL_INIT_VIDEO);
window = SDL_CreateWindow(
"an SDL2 Window",
20,
20,
640,
480,
SDL_WINDOW_OPENGL);
if (window == NULL)
{
printf("Could not create window: %s\n", SDL_GetError());
return 1;
}
SDL_Delay(3000);
SDL_DestroyWindow(window);
SDL_Quit();
return 0;
}

This will install everything necessary to build programs that use SDL: sudo apt-get install libsdl2-dev
Create a new Eclipse project.
Go to properties of the project
C/C++ Build
Settings
GCC C++ Linker -> Libraries
Click on Add... and type SDL2
Apply and reindex the project
I used this documentation. Tested with SDL CreateWindow.
