# This is current meant to be run manually, occasionally:
# - Run then zip the contents of vulkanArtifact/ into e.g. vulkan_windows_libs_1.4.326
# - Upload as an attachment to https://github.com/ocornut/imgui/pull/8925 then change filename in build.yml
# - There is a build_windows_vulkan_libs.yml in commit history that we removed thinking this is run so rarely we don't need to pollute CI UI with it.
