Thanks for reporting, see the discussion in this topic:

It looks like as of Nov 2, the “brownout” of the git:// protocol is beginning. Cloning of DCMTK using this protocol during the build fails, but the solution is just to un-check Slicer\_USE\_GIT\_PROTOCOL in CMake. Should this be the default now, as git:// protocol is truly going away?
