On Windows it is not a symlink but a copy.  Either way the link
or copy could be picked up by ExternalData_LINK_CONTENT when
CMake runs and assumed to be a manually-placed new copy of the
original file.  At that point it will get renamed to
".ExternalData_$algo_$hash" again.

If you write the .md5 (content link) files by hand then you
do not need to enable ExternalData_LINK_CONTENT and can do what
you want.
