# Create the link to VulkanModule, which this project consumes as a PEER library:
#	one checkout of the module, shared by every project that uses it, rather than a
#	private copy per project.  Run once after cloning.  Safe to re-run.
#
#	  GitHub/
#	    HelloVulkanSDL/   <- you are here
#	    VulkanModule/     <- the peer
#
# The link itself is committed, so a fresh clone already has it; this script exists to
#	report clearly when its target is missing, and to clone the module if you ask it to.
