ERROR: libclc shader missing. Consider installing the libclc package
Aborted (core dumped)
I've installed every clc-related package I could find. I've tried
several options for the 'intel-clc' option without luck.
BTW, the description of intel-clc in meson_options.txt looks suspect:
option(
'intel-clc',
type : 'combo',
deprecated: {'true': 'enabled', 'false': 'disabled'},
value : 'disabled',
choices : [
'enabled', 'disabled', 'system',
],
description : 'Build the intel-clc compiler (enables Vulkan Intel ' +
'Ray Tracing on supported hardware).'
)
The default is 'disabled' but that's deprecated? Choices include
'enabled' but that's deprecated too?
Any tips for building the ToT Intel Vulkan driver?

You need to have libclc-NN-dev installed matching with the llvm version,
which on stock 22.04 would be libclc-13-dev.
I'm using llvm 15 and have libclc-15-dev installed. I get the "ERROR:
libclc shader missing. Consider installing the libclc package" issue I
quoted above.
I have llvm 15 installed because I also want to build the radv Vulkan
driver.
