CMake Deprecation Warning at Modules/ThirdParty/GDCM/src/gdcm/Utilities/socketxx/CMakeLists.txt:3 (cmake_policy):
The OLD behavior for policy CMP0022 will be removed from a future version
of CMake.
The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.
Fixing that does not seem hard - it is only for Socket++, and its CMakeLists is not big. I suppose this fix should be applied upstream and then GDCM simply updated? Is anyone familiar with GDCM contribution process?
