Make cannot match the target - c++

Question

I am working on my first makefile, so far this much done.
BUILD = build
BIN = bin
OUTPUTNAME = game.out
INCLUDE = /internalLibraries/include
SRCFILES := $(wildcard src/*.cpp)
OBJFILES := $(patsubst %.cpp,%.o,$(SRCFILES))
OBJFILES := $(foreach dir,$(OBJFILES),$(subst src/,,$(dir)))
DIR := $(dir $(OBJFILES))
$(foreach d,$(DIR),$(shell mkdir -p $(BUILD)/$(d)))
$(shell mkdir -p $(BIN))
CC = g++
CFLAGS = -g -std=c++11
LIBS=-lsfml-graphics -lsfml-window -lsfml-system
G++_VER_LT48 := $(shell expr `$(CC) -dumpversion | cut -f1-2 -d.` \< 4.8 )
ifeq ("$(G++_VER_LT48)","1")
$(error old version of g++ not supported, upgrade to 4.8 or higher)
endif
default: $(BIN)/$(OUTPUTNAME)
$(info $(OBJFILES))
$(BIN)/$(OUTPUTNAME): $(BUILD)/$(OBJFILES)
$(CC) $(CFLAGS) -o $(BIN)/$(OUTPUTNAME) $(BUILD)/main.o $(BUILD)/game.o $(BUILD)/food.o $(BUILD)/snake.o $(LIBS)
$(BUILD)/%.o: %.cpp
$(CC) -c $(CFLAGS) $< -o $# -I $(INCLUDE)
the problem is, running this produces the output:
sidhin#DRAGONHEART:/mnt/c/Users/sidhi/Desktop/Projects/sfml-snake$ make
food.o game.o main.o snake.o
make: *** No rule to make target `build/food.o', needed by `bin/game.out'. Stop.
What is the problem, I cannot make it out.

Answer 1

$(BUILD)/%.o: %.cpp
With BUILD set to "build", this specifies the rule for building a target called "build/food.o" from "food.cpp".
The problem is, obviously, that "food.cpp" does not exist. The actual source file is "src/food.cpp", based on your declaration:
SRCFILES := $(wildcard src/*.cpp)
