# A sample Makefile for building Google Test and using it in user
# tests.  Please tweak it to suit your environment and project.  You
# may want to move it to your project's root directory.
#
# SYNOPSIS:
#
#   make [all]  - makes everything.
#   make TARGET - makes the given target.
#   make clean  - removes all files generated by make.

# Please tweak the following variable definitions as needed by your
# project, except GTEST_HEADERS, which you can use in your own targets
# but shouldn't modify.

# Points to the root of Google Test, relative to where this file is.
# Remember to tweak this if you move this file.
GTEST_DIR = ${GTEST_DIR}

# Where to find user code.
USER_DIR = .

# Flags passed to the preprocessor.
CPPFLAGS += -I\$(GTEST_DIR)/include

# Flags passed to the C++ compiler.
CXXFLAGS += -g -Wall -Wextra -O0 ${EXTRA_DEFINES}

# All tests produced by this Makefile.  Remember to add new tests you
# created to the list.
TESTS = ${SRS_TRUNK_PREFIX}/${SRS_OBJS_DIR}/${APP_NAME}

# All Google Test headers.  Usually you shouldn't change this
# definition.
GTEST_HEADERS = \$(GTEST_DIR)/include/gtest/*.h \\
                \$(GTEST_DIR)/include/gtest/internal/*.h

# House-keeping build targets.

all : \$(TESTS)

clean :
	rm -f \$(TESTS) gtest.a gtest_main.a *.o

# Builds gtest.a and gtest_main.a.

# Usually you shouldn't tweak such internal variables, indicated by a
# trailing _.
GTEST_SRCS_ = \$(GTEST_DIR)/src/*.cc \$(GTEST_DIR)/src/*.h \$(GTEST_HEADERS)

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

# function.
