    Project setup

Quick and clean project setup with cmake and git submodules. We are using
SFML and glm as examples of binary and header only dependencies. I've messed around
with conan, hunter, vcpkg and CPM.cmake and I just get more of a headache than I had
before so I just use this method. I've tested this in clion and visual studio.
The directories are setup thusly...
ROOT
    .gitignore
    CMakeLists.txt
    modules/.git-keep
    src/main.cpp

Get git sorted first
git init
git add .
git commit -a -m "initial mess"

Add sfml as a submodule
> git submodule add https://github.com/SFML/sfml modules/sfml

NOTE: be sure to add modules\sfml to .gitignore

GLM

glm is a header only lib so it's a bit different
git submodule add https://github.com/g-truc/glm modules/glm

NOTE: be sure to add modules\glm to .gitignore
then in CMakeLists.txt we just need to be able to find it
