Instead of
qputenv("QT_VULKAN_DEVICE_EXTENSIONS", "VK_KHR_get_memory_requirements2;VK_NV_ray_tracing");
one can now do
params.deviceExtensions = { "VK_KHR_get_memory_requirements2", "VK_NV_ray_tracing" };
on the QRhiVulkanInitParams passed to QRhi::create().
The environment variable stays important for Qt Quick applications, which provide no
configurability for the QRhi construction (yet). On the other hand, applications using
QRhi directly can now also use the new approach to specify the list of device extensions
to enable.
In addition, take QVulkanInfoVector<QVulkanExtension> into use. There is no reason not to
rely on the infrastructure provided by QVulkanInstance. This also implies showing an
informative warning for unsupported extensions, instead of merely failing the device
creation. (applications will likely not be able to recover of course, but at least the
reason for failing is made obvious this way)
