Yes, but apparently not with options that cause CMake/itkOpenCL.cmake to
be included.  Every call to add_dependencies in that file is incorrect.  The
add_dependencies command is for inter-target ordering dependencies, not
file-level dependencies.  CMP0046 was added in part to start diagnosing
such incorrect code.
