### Autotools
Finding GoogleTest in Autoconf and using it from Automake is also fairly easy:
In your `configure.ac`:
```
AC_PREREQ([2.69])
AC_INIT([my_gtest_pkgconfig], [0.0.1])
AC_CONFIG_SRCDIR([samples/sample3_unittest.cc])
AC_PROG_CXX
PKG_CHECK_MODULES([GTEST], [gtest_main])
AM_INIT_AUTOMAKE([foreign subdir-objects])
AC_CONFIG_FILES([Makefile])
AC_OUTPUT
```
and in your `Makefile.am`:
```
check_PROGRAMS = testapp
TESTS = $(check_PROGRAMS)
testapp_SOURCES = samples/sample3_unittest.cc
testapp_CXXFLAGS = $(GTEST_CFLAGS)
testapp_LDADD = $(GTEST_LIBS)
```
### Meson
Meson natively uses pkgconfig to query dependencies:
```
project('my_gtest_pkgconfig', 'cpp', version : '0.0.1')
gtest_dep = dependency('gtest_main')
testapp = executable(
'testapp',
files(['samples/sample3_unittest.cc']),
dependencies : gtest_dep,
install : false)
test('first_and_only_test', testapp)
```
### Plain Makefiles
Since `pkg-config` is a small Unix command-line utility, it can be used in
handwritten `Makefile`s too:
```makefile
GTEST_CFLAGS = `pkg-config --cflags gtest_main`
GTEST_LIBS = `pkg-config --libs gtest_main`
.PHONY: tests all
tests: all
./testapp
all: testapp
testapp: testapp.o
$(CXX) $(CXXFLAGS) $(LDFLAGS) $< -o $@ $(GTEST_LIBS)
testapp.o: samples/sample3_unittest.cc
$(CXX) $(CPPFLAGS) $(CXXFLAGS) $< -c -o $@ $(GTEST_CFLAGS)
```
