# This script is to be called (ideally from a git-sync-to alias script):
#     cmake -DSYNC_TO_MODULE="$1" -DSYNC_TO_BRANCH="$2" -P cmake/QtSynchronizeRepo.cmake

# Or as follows (ideally from a git-qt-foreach alias script):
#     cmake -DQT_FOREACH=TRUE "-DARGS=$*" -P cmake/QtSynchronizeRepo.cmake
#
# The script can take additional options.
#
# SYNC_REF_SPEC - an alias for SYNC_TO_BRANCH, can be a tag, branch or commit sha1.
#
# REMOTE_NAME - remote name to use for fetching, default is origin.
#
# GIT_DEPTH - corresponds to git's --depth option, will be passed to git clone and git submodule
# update --init operations.
#
# SHOW_PROGRESS - passes --progress to git submodule update operations
#
# VERBOSE - enables more verbose output
#
# The script also takes the following environment variables:
#
# QT_TL_SUBMODULE_UPDATE_FLAGS - additional flags to pass to git submodule update calls.
#
# To run the script in full debug mode use:
# cmake -DSYNC_TO_MODULE="$1" -DSYNC_TO_BRANCH="$2" -DSHOW_PROGRESS=1 -DVERBOSE=1
#       -P cmake/QtSynchronizeRepo.cmake --log-level=DEBUG --trace-redirect=log.txt --trace-expand
