I started testing the patch in Slackware 14.1, which uses cmake 2.8.12. I have not yet tested backwards compatibility with older versions of cmake. Thus far I saw no cmake warnings in arts (good!), but tdelibs is filled with many instances of a single CMP0022 warning: CMake Error: Error evaluating generator expression: $<LINK_ONLY:-Wl,-whole-archive> $<LINK_ONLY> expression requires exactly one parameter. CMake Warning (dev) in tdecore/tdehw/networkbackends/network- manager/CMakeLists.txt: Policy CMP0022 is not set: INTERFACE_LINK_LIBRARIES defines the link interface. Run "cmake --help-policy CMP0022" for policy details. Use the cmake_policy command to set the policy and suppress this warning. Static library target "network_manager_backend-static" has a INTERFACE_LINK_LIBRARIES property. This should be preferred as the source of the link interface for this library. Ignoring the property and using the link implementation as the link interface instead. This warning is for project developers. Use -Wno-dev to suppress it. I am not seeing any of the original warning messages. Darrell
