Hello Constantine,

I'm investigating the same issue right in this moment...

How do you set ${proj}_GIT_TAG? If it a tag or a commit hash it should
work, therefore if you change it in your superbuild, your repository
should be updated.

Unfortunately it doesn't work for branches. Therefore if you set it to
"master" it will work for the clone, but it won't work for the updates,
because the branch "master" is your local branch not the remote one
("origin/master")

Perhaps this should be fixed somehow, either the documentation of the
module to explicitly state this, or the module itself to pull from the
remote branch if GIT_TAG is a branch.


Cheers,
 Daniele
