 This works because `gmock_main` library is compiled with Google Test.
 
-#### Preparing to Build (Unix only) ####
-
-If you are using a Unix system and plan to use the GNU Autotools build
-system to build Google Mock (described below), you'll need to
-configure it now.
-
-To prepare the Autotools build system:
-
-    cd googlemock
-    autoreconf -fvi
-
-To build Google Mock and your tests that use it, you need to tell your
-build system where to find its headers and source files.  The exact
-way to do it depends on which build system you use, and is usually
-straightforward.
-
-This section shows how you can integrate Google Mock into your
-existing build system.
-
-Suppose you put Google Mock in directory `${GMOCK_DIR}` and Google Test
-in `${GTEST_DIR}` (the latter is `${GMOCK_DIR}/gtest` by default).  To
-build Google Mock, create a library build target (or a project as
-called by Visual Studio and Xcode) to compile
-
-    ${GTEST_DIR}/src/gtest-all.cc and ${GMOCK_DIR}/src/gmock-all.cc
-
-with
-
-    ${GTEST_DIR}/include and ${GMOCK_DIR}/include
-
-in the system header search path, and
-
-    ${GTEST_DIR} and ${GMOCK_DIR}
-
-in the normal header search path.  Assuming a Linux-like system and gcc,
-something like the following will do:
-
-    g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-        -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
-        -pthread -c ${GTEST_DIR}/src/gtest-all.cc
-    g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-        -isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
-        -pthread -c ${GMOCK_DIR}/src/gmock-all.cc
-    ar -rv libgmock.a gtest-all.o gmock-all.o
-
-(We need -pthread as Google Test and Google Mock use threads.)
-
-Next, you should compile your test source file with
-${GTEST\_DIR}/include and ${GMOCK\_DIR}/include in the header search
-path, and link it with gmock and any other necessary libraries:
-
-    g++ -isystem ${GTEST_DIR}/include -isystem ${GMOCK_DIR}/include \
-        -pthread path/to/your_test.cc libgmock.a -o your_test
-
-As an example, the make/ directory contains a Makefile that you can
-use to build Google Mock on systems where GNU make is available
-(e.g. Linux, Mac OS X, and Cygwin).  It doesn't try to build Google
-Mock's own tests.  Instead, it just builds the Google Mock library and
-a sample test.  You can use it as a starting point for your own build
-script.
-
-If the default settings are correct for your environment, the
-following commands should succeed:
-
-    cd ${GMOCK_DIR}/make
-    make
-    ./gmock_test
-
-If you see errors, try to tweak the contents of
-[make/Makefile](make/Makefile) to make them go away.
-
-### Windows ###
-
-The msvc/2005 directory contains VC++ 2005 projects and the msvc/2010
-directory contains VC++ 2010 projects for building Google Mock and
-selected tests.
-
-Change to the appropriate directory and run "msbuild gmock.sln" to
-build the library and tests (or open the gmock.sln in the MSVC IDE).
-If you want to create your own project to use with Google Mock, you'll
-have to configure it to use the `gmock_config` propety sheet.  For that:
-
- * Open the Property Manager window (View | Other Windows | Property Manager)
- * Right-click on your project and select "Add Existing Property Sheet..."
- * Navigate to `gmock_config.vsprops` or `gmock_config.props` and select it.
- * In Project Properties | Configuration Properties | General | Additional
-   Include Directories, type <path to Google Mock>/include.

-The `gmock-config' script provides access to the necessary compile and linking
-flags to connect with Google C++ Mocking Framework, both in a build prior to
-installation, and on the system proper after installation. The installation
-overrides may be issued in combination with any other queries, but will only
-affect installation queries if called on a built but not installed gmock. The
-installation queries may not be issued with any other types of queries, and
-only one installation query may be made at a time. The version queries and
-compiler flag queries may be combined as desired but not mixed. Different
-version queries are always combined with logical "and" semantics, and only the
-last of any particular query is used while all previous ones ignored. All
-versions must be specified as a sequence of numbers separated by periods.
-Compiler flag queries output the union of the sets of flags when combined.
-
- Examples:
-  gmock-config --min-version=1.0 || echo "Insufficient Google Mock version."
-
-  g++ $(gmock-config --cppflags --cxxflags) -o foo.o -c foo.cpp
-  g++ $(gmock-config --ldflags --libs) -o foo foo.o
-
-  # When using a built but not installed Google Mock:
-  g++ $(../../my_gmock_build/scripts/gmock-config ...) ...
-
-  # When using an installed Google Mock, but with installation overrides:
-  export GMOCK_PREFIX="/opt"
-  g++ $(gmock-config --libdir="/opt/lib64" ...) ...

-  --exec-prefix              executable installation prefix
-  --libdir                   library installation directory
-  --includedir               header file installation directory
-  --version                  the version of the Google Mock installation
-

-  --exact-version=VERSION    return 0 if the version is exactly VERSION
-  --max-version=VERSION      return 0 if the version is at most VERSION

 system where to find its headers and source files. The exact way to do it
 depends on which build system you use, and is usually straightforward.
 
-#### Build
-
-Suppose you put Google Test in directory `${GTEST_DIR}`. To build it, create a
-library build target (or a project as called by Visual Studio and Xcode) to
-compile
-
-    ${GTEST_DIR}/src/gtest-all.cc
-
-with `${GTEST_DIR}/include` in the system header search path and `${GTEST_DIR}`
-in the normal header search path. Assuming a Linux-like system and gcc,
-something like the following will do:
-
-    g++ -std=c++11 -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-        -pthread -c ${GTEST_DIR}/src/gtest-all.cc
-    ar -rv libgtest.a gtest-all.o
-
-(We need `-pthread` as Google Test uses threads.)
-
-Next, you should compile your test source file with `${GTEST_DIR}/include` in
-the system header search path, and link it with gtest and any other necessary
-libraries:
-
-    g++ -std=c++11 -isystem ${GTEST_DIR}/include -pthread path/to/your_test.cc libgtest.a \
-        -o your_test
-
-As an example, the make/ directory contains a Makefile that you can use to build
-Google Test on systems where GNU make is available (e.g. Linux, Mac OS X, and
-Cygwin). It doesn't try to build Google Test's own tests. Instead, it just
-builds the Google Test library and a sample test. You can use it as a starting
-point for your own build script.
-
-If the default settings are correct for your environment, the following commands
-should succeed:
-
-    cd ${GTEST_DIR}/make
-    make
-    ./sample1_unittest
-
-If you see errors, try to tweak the contents of `make/Makefile` to make them go
-away. There are instructions in `make/Makefile` on how to do it.

-dnl
-dnl @summary figure out how to build C programs using POSIX threads
-dnl
-dnl This macro figures out how to build C programs using POSIX threads.
-dnl It sets the PTHREAD_LIBS output variable to the threads library and
-dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
-dnl C compiler flags that are needed. (The user can also force certain
-dnl compiler flags/libs to be tested by setting these environment
-dnl variables.)
-dnl
-dnl Also sets PTHREAD_CC to any special C compiler that is needed for
-dnl multi-threaded programs (defaults to the value of CC otherwise).
-dnl (This is necessary on AIX to use the special cc_r compiler alias.)
-dnl
-dnl NOTE: You are assumed to not only compile your program with these
-dnl flags, but also link it with them as well. e.g. you should link
-dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
-dnl $LIBS
-dnl
-dnl If you are only building threads programs, you may wish to use
-dnl these variables in your default LIBS, CFLAGS, and CC:
-dnl
-dnl        LIBS="$PTHREAD_LIBS $LIBS"
-dnl        CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
-dnl        CC="$PTHREAD_CC"
-dnl
-dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
-dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
-dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
-dnl
-dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
-dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
-dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
-dnl default action will define HAVE_PTHREAD.
-dnl
-dnl Please let the authors know if this macro fails on any platform, or
-dnl if you have any other suggestions or comments. This macro was based
-dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with
-dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros
-dnl posted by Alejandro Forero Cuervo to the autoconf macro repository.
-dnl We are also grateful for the helpful feedback of numerous users.
