Attempt to build

Steps taken:

1. Build sfml locally and output to SFML_souren dir

   ➜  git clone https://github.com/SFML/SFML.git
   ➜  SFML git:(master) cmake -DBUILD_SHARED_LIBS=false -S . -B ../SFML_souren

2. Build ungroup

   ➜  ungroup_game git:(...) ✗ cmake -DSFML_DIR="/Users/peco/Documents/code/SFML_souren" -DUNGROUP_STATIC=TRUE -S . -B build
   -- Found SFML 2.5.1 in /Users/peco/Documents/code/SFML_souren
   -- Found Boost: /usr/local/include (found suitable version "1.70.0", minimum required is "1.55")
   -- Configuring done
   -- Generating done
   -- Build files have been written to: /Users/peco/Documents/code/ungroup_game/build

   ➜ ungroup_game git:(...) ✗ cmake --build build -- -j
