The --tags option belongs to "git fetch" and extra flags can
be added for that by setting CTEST_GIT_UPDATE_OPTIONS before
calling ctest_update.  Try:

 set(CTEST_GIT_UPDATE_OPTIONS "--tags")
 ...
 ctest_update()

Alternatively one may configure the Git repo with

 git config remote.origin.tagopt "--tags"

so that "git fetch" does it automatically.
