# To lower build times, we avoid running the fetchDependencies script if the MoltenVK
# version didn't change. The last-built MoltenVK version is stored inside a file in
# the timestamp directory. If the file doesn't exist or the file contains a different
# MoltenVK version, fetchDependencies is ran.
#
# Usage: configure.sh <timestamp directory> <source directory> <MoltenVK version>
