The Apple macOS platform using the most recent version of 
XCode and the Clang C++ compiler already contains all the files 
necessary except for sgl.h and
sgl.hpp.  Programmers can place these 
sgl.h and sgl.hpp
files
in a convenient folder anywhere and configure their XCode project
to reference this folder as an additional include directory.
As an alternative, macOS developers may place the 
sgl.h or sgl.hpp in their
current build directory and use the following preprocessor
#include directive:
#include "sgl.hpp"
or
#include "sgl.h"
as appropriate (see the first part of Section SGL Application Architecture that explains how to use the header files).
