# 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.

# We have no idea here whether pthreads is available in the system, so

# disable its use.

CPPFLAGS += -I$(FUSED_GTEST_DIR) -DGTEST_HAS_PTHREAD=0

# Flags passed to the C++ compiler.
