# Vulkaninfo Application Bundle

# We already have a "vulkaninfo" target, so create a new target with a different name
# and use the OUTPUT_NAME property to rename the target to the desired name.
# The standalone binary is called "vulkaninfo" and the bundle is called "vulkaninfo.app".
# Note that the executable is a script that launches Terminal to see the output.
