Accept NEW CMake policies up to CMake 3.14 (#4112)

Browse Source 
Starting with CMake 3.27, deprecation warnings are issued
when asking for policy settings for CMake 3.4 or earlier.
The cmake_minimum_required() command accepts a version
range, which allows NEW policy settings up to the upper end
of that range to be used, but without raising the minimum
CMake version above the bottom of that range. This means
NEW policy settings will be used where available, without
requiring them. This change updates the project's
cmake_minimum_required() calls to use a version range to
extend the upper policy version to 3.14 where it wasn't already
at that version or higher. This prevents the deprecation warning
from CMake 3.27, and gives breathing space before a future
CMake release will start issuing similar deprecation warnings
again.
