cmake-2.12.1 + kde*-4.12

[Treeve Jelbert]

I have cmake-2.12.1 installed and use to build frameworks.

When I use it to build  kde*-4.12 I get lots of warnings of the type:

-- Configuring done
CMake Warning (dev) in kdecore/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.

  Target "kdecore" has an INTERFACE_LINK_LIBRARIES property which differs
  from its LINK_INTERFACE_LIBRARIES properties.

  INTERFACE_LINK_LIBRARIES:

    Qt4::QtCore;-
lpthread;Qt4::QtNetwork;Qt4::QtDBus;Qt4::QtXml;/usr/lib/libz.so;/usr/lib/libbz2.so;/usr/lib/liblzma.so;resolv;-
lpthread;/usr/lib/libfam.so;Qt4::QtDBus;Qt4::QtCore;-lpthread

  LINK_INTERFACE_LIBRARIES:

    Qt4::QtDBus;Qt4::QtCore;-lpthread

This warning is for project developers.  Use -Wno-dev to suppress it.
