COMP: Support namespaced targets in updated DCMTK CMake exports

This update maintains backward compatibility while enabling support for DCMTK's
namespaced CMake targets, introduced in commit DCMTK/dcmtk@c684bb3 ("Various enhancements for DCMTK's CMake exports.", 2021-07-05).

In this version, target names are prefixed with "DCMTK::", requiring adjustments
to the build system ensuring the variable KIT_target_libraries is properly
set.
