# WARNING!
# OTB uses Git-LFS to store the (large) tests data.
# Git-LFS is mostly transparent for the user and recent versions
# are able to use Git-LFS quite efficiently.
# But Git fails to manage efficiently numerous LFS data.
# We have to use directly git-lfs wrapping commands to have an
# efficient cloning step.
# Furthermore, Git-LFS and Gitlab sufer a bug preventing usage of
# GIT_STRATEGY=fetch (https://gitlab.com/gitlab-org/gitlab-runner/issues/3318)
