[PATCH v2 vkd3d 1/4] build: Drop hack for stripping RPC includes from widl-generated headers.

[Sveinar Søpler]

There is no such thing as "get those easily from.." when it comes to Luanchpad PPA, or OBS. Cos the ONLY option afaik is either a: From "official" repo's, or b: build yourself so that the package builder have access to it from "itself".

So, when it comes to creating a installable package like i did with libFAudio, i would need (as you say) libvulkan-headers. Those headers i guess could be patched into the build-source as a external download/dep kind of thingy perhaps? And then just make wine depend on >libvulkan-1.1.84, and its up to the users to figure that out? I dunno if its interesting anyway for WineHQ to build wine-devel with vkd3d support for anything older than the unreleased Ubuntu Disco on their package repo tho. And seeing wined3d making a move towards vulkan might require newer vulkan headers there too?

So, the next question might be: Will WineHQ in the future only be a "newest and/or beta distro only" kind of package? :)

Ill look into perhaps creating widl as a standalone package for the PPA buildbot as a retro-fit thing for bionic/cosmic perhaps... 
It turns out that using: 
export WIDL="/usr/lib/wine/widl" does not work, but using
export WIDL=/usr/lib/wine/widl does work.

Guess thats just another "noob mistake", that is totally different than noob mistake :) Ah well...

Strictly speaking, you don't need libvulkan to build vkd3d. The build
without libvulkan requires that any client of libvkd3d must pass a
pointer to vkGetInstanceProcAddr() to vkd3d_create_instance(). A build
without libvulkan is good enough for Wine. You need recent Vulkan
headers, but you can get those easily from
git at github.com:KhronosGroup/Vulkan-Headers.git (just add the path to
headers to CPPFLAGS passed to configure). Similarly, a new version of
widl shouldn't be a big problem. If you have recent enough Wine
sources, you can also build a recent version of widl: make tools/widl.
