Subject: [bug#66413] [PATCH] gnu: mangohud: Update to 0.7.0.

From: John Kehayias <[email-masked]>
Date: Mon, 09 Oct 2023 04:23:30 +0000

* gnu/packages/graphics.scm (mangohud): Update to 0.7.0.
[arguments]<#:configure-flags>: Remove "-Duse_system_vulkan=enabled" and
"-Dvulkan_datadir" from as they are no longer supported.
<#:phases>: Add 'unbundle-vulkan-headers'.
[inputs]: Add nlohmann-json.  Replace vulkan-headers with origin for
[email-masked].
[native-inputs]: Add git-minimal.
---

Here is a patch to update mangohud to the latest version. I've used
guix lint, built it locally, and also tested it works with vulkan. The
major change here is to manually unbundle vulkan-headers as that is no
longer a configurable option. To do this a bare origin is used to get
the source for the expected vulkan version (a specific older one is
required) and the build patched to use this.

Thanks!
John
