+### 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)
+```
