# A Makefile for fusing Google Test and building a sample test against it.
#
# SYNOPSIS:
#
#   make [all]  - makes everything.
#   make TARGET - makes the given target.
#   make check  - makes everything and runs the built sample test.
#   make clean  - removes all files generated by make.

# Points to the root of fused Google Test, relative to where this file is.
FUSED_GTEST_DIR = output

# Paths to the fused gtest files.
FUSED_GTEST_H = $(FUSED_GTEST_DIR)/gtest/gtest.h
FUSED_GTEST_ALL_CC = $(FUSED_GTEST_DIR)/gtest/gtest-all.cc

# Where to find the sample test.
SAMPLE_DIR = ../../samples

# Where to find gtest_main.cc.
GTEST_MAIN_CC = ../../src/gtest_main.cc

# Flags passed to the preprocessor.
CPPFLAGS += -I$(FUSED_GTEST_DIR)

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