### 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)
 | 
					 | 
				
			||||||
```
 | 
					 | 
				
			||||||
 | 
					 | 
				
			||||||
