# Provide an option to control the -std argument for the C++ compiler.
# We don't use CMAKE_CXX_STANDARD since it requires at least CMake 3.8
# to support C++17.

# Most users probably want to stick with the default here. However, gnu++1z
# does change the linkage of how some symbols are emitted (e.g., constexpr
# variables defined in headers). In case this causes problems for downstream
# libraries that aren't using gnu++1z yet, provide an option to let them still
# override this with gnu++14 if they need to.
