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.  Usually you shouldn't change this
35# definition.

52# For simplicity and to avoid depending on Google Test's
53# implementation details, the dependencies specified below are
54# conservative and not optimized.  This is fine as Google Test
55# compiles fast and for ordinary users its source rarely changes.
