-*   Physac - Physics movement
-*
-*   NOTE 1: Physac requires multi-threading, when InitPhysics() a second thread is created to manage physics calculations.
-*   NOTE 2: Physac requires static C library linkage to avoid dependency on MinGW DLL (-static -lpthread)
-*
-*   Use the following line to compile:
-*
-*   gcc -o $(NAME_PART).exe $(FILE_NAME) -s -static  /
-*       -lraylib -lpthread -lglfw3 -lopengl32 -lgdi32 -lopenal32 -lwinmm /
-*       -std=c99 -Wl,--subsystem,windows -Wl,-allow-multiple-definition
