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. 17 GTEST_DIR = .. 18 19 # Where to find user code. 20 USER_DIR = ../samples 21 22 # Flags passed to the preprocessor. 23 CPPFLAGS += -I$(GTEST_DIR) -I$(GTEST_DIR)/include 24 25 # Flags passed to the C++ compiler. 26 CXXFLAGS += -g -Wall -Wextra 27 28 # All tests produced by this Makefile. Remember to add new tests you 29 # created to the list. 30 TESTS = sample1_unittest 31 32 # All Google Test headers.
