Fixed IncompatibleDriver error while building examples by installing the Vulkan SDK

[cies]

When trying to build+run an example (my first attempt to get going with Nannou) I got the following error:

thread 'main' panicked at 'failed to create vulkan instance: IncompatibleDriver', src/libcore/result.rs:1165:5

The suggested fixes in this issue tracker did not help. I found a someone saying: if you can get a vulkan thing to build in C then you should be able to get it to build in Rust. That sounded wise. It also pointed to the Vulkan SDK...

https://vulkan.lunarg.com/doc/sdk

...that contains some examples. So I got going. Had to upgrade cmake and install some sys deps (some x11 shizzle) in the process. After I got ./vulkansdk samples to succeed (did not even run any of 'm) I also managed to get the Nannou example to build.

I'm just reporting this for someone else to maybe get a pointer in the right direction.

Keywords: linux (old ubuntu version, 16.04), cmake, vulkan, driver, IncompatibleDriver, build error, examples.

Extra info: specifically the source $PATH_TO_ROOT_OF_VULKAN_SDK/setup-env.sh step of the vulkan sdk story seems to be important. Without it it I still get the same error.

Thanks a lot for the issue @cies!

I just wanted to give you an update that we're hoping to resolve a lot of the macOS Vulkan issues in #438 by targeting metal directly from gfx-hal, rather than going through MoltenVK. I'll likely revisit this once that has been addressed.
