Makefile

# A Makefile based on the Google Test sample Makefile
# https://github.com/google/googletest/blob/master/googletest/make/Makefile
#
# Modified with the help of http://nuclear.mutantstargoat.com/articles/make/
#
# SYNOPSIS:
#
#   make - makes the main file.
#   make clean  - removes all files generated by make.
#   make test - runs all tests

# Create a build directory
BUILD_DIR = build
dummy_build_folder := $(shell mkdir -p $(BUILD_DIR))

# Which compilers to use
CPP=g++ -std=c++11
C=gcc

# Where to find source code.
SRC_DIR = src

# Test code
TEST_DIR = tests

# Where to find build objects
BUILD_DIR = build

# The working directory
CURRENT_DIR = $(shell pwd)

# Dependency header files
DEP_HEADERS = $(SRC_DIR)/*.h
TEST_HEADERS = $(TEST_DIR)/*.h

VPATH = $(SRC_DIR):$(BUILD_DIR)

# Flags passed to the preprocessor.
# Set Google Test's header directory as a system directory, such that
# the compiler doesn't generate warnings in Google Test headers.
CPPFLAGS += -isystem $(GTEST_DIR)/include

# Flags passed to the C++ compiler.
CXXFLAGS += -g -Wall -Wextra -pthread

# C flags
CFLAGS = -std=c99

# Graphics flags
GRAPHICSFLAGS = -lglut -lGL -lGLU

# ncurses flag
LDFLAGS = -lncurses

# The Makefile's run command
RUN = $(BUILD_DIR)/ttetris

# Build targets.
.PHONY: all
all : $(RUN)
	LD_LIBRARY_PATH=$(CURRENT_DIR)/build
