#### C++ Standard Version
An environment that supports C++11 is required in order to successfully build
Google Test. One way to ensure this is to specify the standard in the top-level
project, for example by using the `set(CMAKE_CXX_STANDARD 11)` command. If this
is not feasible, for example in a C project using Google Test for validation,
then it can be specified by adding it to the options for cmake via the
`DCMAKE_CXX_FLAGS` option.
