So far GParted includes Google Test 1.8.1 [1], which was the latest
release which supported pre-C++11 compilers [2]. Now that GParted
requires C++11 compilation, update to Google Test 1.10.0. Replace the
following files and directories from Google Test 1.10.0:
LICENSE
README.md
include/
src/
Note the LICENSE file is identical, where as the other files have
changed. This includes file additions and removals, hence the change
to Makefile.am too.
Even though Google Test releases up to and including 1.12.1 are
compilable with C++11 compilers [3], it is not possible to upgrade
beyond Google Test 1.10.0 at this time because later releases fail to
compile on on still supported RHEL / CentOS 7 with this error:
$ cd lib/gtest
$ make check
...
./include/gtest/gtest-matchers.h:414:12: error: 'is_trivially_copy_constructible' is not a member of 'std'
std::is_trivially_copy_constructible<M>::value &&
^
This failure turns out to be because GCC libstdc++ 4.8.5 doesn't include
is_trivially_copy_constructible et al [4][5].

Closes!117 - Require C++11 compilation
Update to Google Test C++ test framework from release 1.8.0 to 1.8.1.
Replace the following files and directories from Google Test 1.8.1:
LICENSE
README.md
include/
src/
Note the LICENSE file is identical, where as the other files changed.
Also see commit which initially added Google Test:
87f7170a55
Add Google Test 1.8.0 files (#781978)
This closely follows the minimal-gtest-autotools template project.
https://github.com/octol/minimal-gtest-autotools
Now 'make check' will additionally build the Google Test C++ test
framework libraries.
Bug 781978 - Add Google Test C++ test framework
Copy the Google Test C++ test framework (subset needed to build the unit
testing libraries) into the GParted project. Copy the following files
and directories from Google Test, release 1.8.0:
LICENSE
README.md
include/
src/
into lib/gtest/. All the files are under the BSD license as documented
in lib/gtest/LICENSE.
