1# A sample Makefile for building Google Test and using it in user 2# tests. Please tweak it to suit your environment and project. You 3# may want to move it to your project's root directory. 4# 5# SYNOPSIS: 6# 7# make [all] - makes everything. 8# make TARGET - makes the given target. 9# make clean - removes all files generated by make. 10 11# Please tweak the following variable definitions as needed by your 12# project, except GTEST_HEADERS, which you can use in your own targets 13# but shouldn't modify. 14 15# Points to the root of Google Test, relative to where this file is. 16# Remember to tweak this if you move this file. 17GTEST_DIR = .. 18 19# Where to find user code. 20USER_DIR = ../samples 21 22# Flags passed to the preprocessor. 23# Set Google Test's header directory as a system directory, such that 24# the compiler doesn't generate warnings in Google Test headers. 25CPPFLAGS += -isystem $(GTEST_DIR)/include 26 27# Flags passed to the C++ compiler. 28CXXFLAGS += -g -Wall -Wextra -pthread 29 30# All tests produced by this Makefile. Remember to add new tests you 31# created to the list. 32TESTS = sample1_unittest 33 34# All Google Test headers.
