Set CMake Policies CMP0025 and CMP0042 as necessary

CMake 3.0 introduces these policies to improve default behavior on OS X.
Set them explicitly in VTK to avoid policy warnings.  VTK already works
with the NEW behavior.

Policy CMP0025 affects the project() command when the Apple Clang
compiler is used so we need to set it in all the Examples.  Policy
CMP0042 affects shared libraries on OS X, enabling MACOSX_RPATH by
default.  Set it in directories where we create libraries.  Also tell
KWSys to enable MACOSX_RPATH explicitly instead of setting the policy.
