COMP: Add link interface specification for wrapping target_link_libraries.
COMP: Add link interface specification for wrapping target_link_libraries.

This addresses:

  CMake Warning (dev) at Modules/Bridge/VtkGlue/wrapping/CMakeLists.txt:14 (target_link_libraries):
  Policy CMP0023 is not set: Plain and keyword target_link_libraries
  signatures cannot be mixed.  Run "cmake --help-policy CMP0023" for policy
  details.  Use the cmake_policy command to set the policy and suppress this
  warning.

  The plain signature for target_link_libraries has already been used with
  the target "ITKVtkGluePython".  All uses of target_link_libraries with a
  target should be either all-keyword or all-plain.

  The uses of the plain signature are here:

   * Wrapping/Generators/Python/CMakeLists.txt:428 (target_link_libraries)

Following the module upgrade where public and private link dependencies are specified.
