Nobody would write a Makefile like this one. This one (untested) in the
spirit of Make. It reads: to build all (the default target here) one
needs all the .o files corresponding to the .cpp files listed in the
SRCS valiable; to build a .o from a .cpp call $(CPP) ...
all: $(SRCS:%.cpp=$(BUILD)/%.o)
$(BUILD)/%.o : %.cpp
$(CPP) $(FLAGS) -c $< -o $@
The GNU Make manual is a really piece of doc...
