A very simple and efficient Makefile for C++, good for course projects!

Makefile

CXX :=g++
CXXFLAGS :=-Wall
SRCS :=$(wildcard *.cpp)
SRCS :=$(filter-out demo.cpp, $(SRCS))
SRCS_H :=$(patsubst %.cpp, %.h, $(SRCS))
OBJS :=$(patsubst %.cpp, %.o, $(SRCS))

all: build

run: build
	./demo

submit:
	zip submission.zip *.h *.cpp *.md Makefile

$(OBJS): $(SRCS) $(SRCS_H)

clean:
	-rm $(OBJS)
	-rm demo

build: demo.cpp $(OBJS)
	$(CXX) $(CXXFLAGS) -o demo demo.cpp $(OBJS)
