Subject: [PATCH] Add CMake version guard around setting C++ standard

It seems like CMake 3.1.3 introduced the C/C++ standard properties,
while the minimum version of this CMake file is 2.8.12. So we do what
FAudio does, which is print a warning if the CMake version is too old
and otherwise use it if we have the feature.
