SOURCES := $(shell find $(SRCDIR) -type f -name *.$(SRCEXT)) # get list of all *.cpp files in directory ./src
OBJECTS := $(patsubst $(SRCDIR)/%,$(BUILDDIR)/%,$(SOURCES:.$(SRCEXT)=.$(OBJEXT))) # replace PATTERN,REPLACEMENT,TEXT
# the : = operator replaces the file extension ".cpp" with ".o" (just replaces text)
# so we have a list of all *.o files in the format ./src/*.o (instead of ./src/*.cpp
# the patsubst (pattern substitution) replaces the "src" with "obj"
# so SOURCES becomes a list of ./src/*.cpp
# and OBJECTS becomes a list of ./obj/*.o
# 1-to-1 correspondance between objects and source files
