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
