Vulkan spinning cube demo application

TLDR

Run Vulkan demo
$ vkcube
With frame count
$ vkcube --c [1000]
Present mode
$ vkcube --present_mode [0]
GPU select
$ vkcube --gpu [0]

SYNOPSIS

vkcube [--c frames] [--presentmode mode] [options_]

DESCRIPTION

vkcube is a simple demo application from the Vulkan SDK that displays a spinning 3D cube rendered using the Vulkan graphics API. It serves as a quick verification tool to confirm that Vulkan drivers and libraries are correctly installed and functioning on the system.The application opens a window showing a textured cube rotating continuously. If the cube renders and spins smoothly, it indicates that the GPU, Vulkan driver, and display system are working together properly. Options allow selecting a specific GPU, setting the presentation mode, and limiting the number of rendered frames.As part of the official Vulkan-Tools package maintained by the Khronos Group, vkcube is the C implementation of the demo (vkcubepp is the C++ version). It is commonly used as a first diagnostic step when troubleshooting Vulkan support on Linux systems.
