# This scope makes it easy to incorporate the Vulkan validation layers into a
# package that is part of the Fuchsia system build.
#
# To use it, import this gni file and add the entries of the
# 'vulkan_validation_layers' scope to the package's 'loadable_modules',
# 'resources', and 'public_deps' parameters.
#
# Example BUILD.gn file:
#
# import("//src/graphics/lib/vulkan/layers.gni")
#
# package("my_funky_vulkan_using_program") {
# loadable_modules = [
# ...
# ] + vulkan_validation_layers.loadable_modules
#
# resources = [
# ...
# ] + vulkan_validation_layers.resources
#
# public_deps = [
# ...
# ] + vulkan_validation_layers.public_deps
# }
#
# This will end up placing the validation libraries within the package's "lib/"
# directory, where they can be loaded like normal libraries, and place the layer
# configuration data in the package's "data/vulkan/explicit_layer.d" directory which
# is mapped to "/config/vulkan/explicit_layer.d"
import("//build_overrides/vulkan_validation_layers.gni")
vulkan_data_dir = "$root_out_dir/$vulkan_data_subdir"
vulkan_validation_layers = {
loadable_modules = [
{
name = "VkLayer_khronos_validation.so"
},
]
resources = [
{
path = rebase_path("$vulkan_data_dir/VkLayer_khronos_validation.json")
dest = "vulkan/explicit_layer.d/VkLayer_khronos_validation.json"
},
]
public_deps = [
"//third_party/Vulkan-ValidationLayers:vulkan_gen_json_files",
"//third_party/Vulkan-ValidationLayers:vulkan_validation_layers",
]
}
