Summary0015799: Way to pass git options for cloning in ExternalProject_Add
DescriptionAFAIK there is no way to pass git options while cloning repositories with ExternalProject_Add.

Cloning git repositories can take a very long time. Git has options that make cloning instantaneous if e.g. only one revision is required. For example: --depth 1 clones only the latest revision very fast.

I would like to be able to pass options to git clone since that would significantly improve my build times, which right now spend a very long time cloning the whole history of multiple git repositories.

It sounds like you want tarballs. Is there some use case where a git --depth 1 repo is preferred over a tarball?

How is cloning the latest commit (and the latest commit only) from a git repository related to tarballs?

Is there a better git command for doing that?

I'm thinking of repos that are on hosting sites like Github or have a Gitweb interface where downloading a tarball of an arbitrary hash is available. If not, then --depth 1 is probably the best thing available.

I seem thanks! Does CMake support downloading a tarbal for an arbitrary hash from github? If not that would be very useful as well!

It looks like if you don't provide a hash value, ExternalProject won't enforce it, but maybe I'm missing something. However, it also appears that it will *always* redownload the file since it can't verify it is valid. I think github has fixed their tarball stability problems at least, so providing a hash should there at least.
