I'm using macos's ability to compile on newer OS for older OS (10_8). I'm getting
warnings about CLOCK_GETTIME_MONOTONIC. A quick grep showed me this code,
but for whatever reason, it's not fixing my problem.

Is there any way to passing some explicit configure/compile argument to force
it to not use clock-monotonic on this build?

# XCode v8 bug: iOS when targeting less than v10, or MacOS when targeting less than v10.12 will
# say clock_gettime exists, it is a weak symbol that only exists in iOS10/MacOS10.12 and will
# cause a crash at runtime when running on older versions. Skip finding CLOCK_MONOTONIC on older
# OS's.
IF ((NOT APPLE) OR IOS_V10 OR MACOS_V1012)
CHECK_SYMBOL_EXISTS (CLOCK_MONOTONIC "${CMAKE_EXTRA_INCLUDE_FILES}" HAVE_CLOCK_GETTIME_MONOTONIC)
ENDIF ()

Thanks,
Ben
