This change adds the --enable-skia-vulkan-validation build option. When this option is set, Skia will be built with Vulkan validation layers enabled. Vulkan validation layers must also be installed on the development machine (e.g. via the Windows Vulkan SDK, or the Ubuntu vulkan-validationlayers package). Vulkan validation layers are an important debugging tool for Vulkan application development. Validation layers externally verify that Vulkan API calls are correct and comply with the standard. This is particularly important as Vulkan does not require drivers to reject invalid uses; some hardware or drivers may tolerate certain developer mistakes, while other drivers reject them. Without using validation layers to confirm, this may create a false impression that certain hardware/drivers are faulty, when it is our own code at fault.

C/C++ Configuration Created by configure Script
These are configuration files for various features as detected by configure.
Include only those files you need (in order to reduce rebuilds when a setting changes).
Settings here are only C/C++ #define directives, so they apply only to C/C++ source,
not to Makefiles.
Adding a New Setting:
- do
AC_DEFINE(HAVE_FOO)inconfigure.acwhen a setting should be set - choose the proper
config_host/config_XXX.hfile to use- if it is a global setting (such as availability of a compiler feature),
use
config_host/config_global.h - otherwise check if there is a matching
config_host/config_XXX.hfile - if none matches, add a new one:
- add
config_host/config_XXX.h.inhere, with just#ifndefinclude guard - add
AC_CONFIG_HEADERS([config_host/config_XXX.h])next to the others inconfigure.ac
- add
- if it is a global setting (such as availability of a compiler feature),
use
- add
#define HAVE_FOO 0to theconfig_host/config_XXX.h, possibly with a comment (do not use#undef HAVE_FOO, unless the setting has more values than on/off) - add
#include <config_XXX.h>before any #ifHAVE_FOOin a source file - make sure you use
#if HAVE_FOOfor on/off settings, do not use#ifdef
