# ==== Define cmake build policies that affect compilation and linkage default behaviors
#
# Set the NEWEST_VALIDATED_POLICIES_VERSION string to the newest cmake version
# policies that provide successful builds. By setting NEWEST_VALIDATED_POLICIES_VERSION
# to a value greater than the oldest policies, all policies between
# OLDEST_VALIDATED_POLICIES_VERSION and CMAKE_VERSION (used for this build)
# are set to their NEW behaivor, thereby suppressing policy warnings related to policies
# between the OLDEST_VALIDATED_POLICIES_VERSION and CMAKE_VERSION.
#
# CMake versions greater than the NEWEST_VALIDATED_POLICIES_VERSION policies will
# continue to generate policy warnings "CMake Warning (dev)...Policy CMP0XXX is not set:"
