BUILDSTDERR:   policies are deprecated and that a policy should be set to OLD only under
BUILDSTDERR:   specific short-term circumstances.  Projects should be ported to the NEW

BUILDSTDERR: CMake Deprecation Warning at CMakeLists.txt:3 (cmake_policy):
BUILDSTDERR:   The OLD behavior for policy CMP0043 will be removed from a future version
BUILDSTDERR:   of CMake.
BUILDSTDERR:   The cmake-policies(7) manual explains that the OLD behaviors of all
BUILDSTDERR:   policies are deprecated and that a policy should be set to OLD only under
BUILDSTDERR:   specific short-term circumstances.  Projects should be ported to the NEW
BUILDSTDERR:   behavior and not rely on setting a policy to OLD.

BUILDSTDERR: CMake Deprecation Warning at CMakeLists.txt:3 (cmake_policy):
BUILDSTDERR:   The OLD behavior for policy CMP0043 will be removed from a future version
BUILDSTDERR:   of CMake.
BUILDSTDERR:   The cmake-policies(7) manual explains that the OLD behaviors of all
BUILDSTDERR:   policies are deprecated and that a policy should be set to OLD only under
BUILDSTDERR:   specific short-term circumstances.  Projects should be ported to the NEW
BUILDSTDERR:   behavior and not rely on setting a policy to OLD.
