# Call this script with the version of the Vulkan-LoaderAndValidationLayers-sdk
# that you would like to fetch the sources for. This will fetch the SDK from
# github, and then look at the revisions listed in the external_revisions
# directory to fetch the proper glslang, SPIRV-Headers, and SPIRV-Tools.
#
# Example:  VERSION=1.1.73.0 ./fetch-sources.sh

VERSION=${VERSION:-1.1.73.0}

# Remove existing sources:
rm -rf Vulkan-LoaderAndValidationLayers-sdk* glslang-* SPIRV-Headers-* SPIRV-Tools-*

# Fetch SDK:
lftpget https://github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers/archive/sdk-${VERSION}/Vulkan-LoaderAndValidationLayers-sdk-${VERSION}.tar.gz
