After running "git fetch" CMake reads .git/FETCH_HEAD to determine
what branch is intended for merge (just as pull does).  This is the
same as "git pull --tags" failing.  You need to specify the remote
and branch explicitly to use pull with --tags:

 set(CTEST_GIT_UPDATE_OPTIONS "--tags origin master")

CMake cannot add this automatically because the entire point of
reading FETCH_HEAD is that CMake does not try to parse the git
config to learn this information.

What is your goal of using --tags?  The ctest_update command's job
is to follow a tracking branch.  What do tags have to do with that?
