Description:
The vulkan-icd-loader package is broken, it ships vulkan-dev and the vulkan runtime in one package without adding vulkan-headers as a "must have" depedency

This breaks the principle of pkg-config in cmake detection, since you can install the icd loader(which also acts as dev package(library wise)) without needing vulkan-headers.

This is not the case on debian:
https://packages.debian.org/de/sid/amd64/libvulkan-dev/filelist

https://packages.debian.org/de/sid/amd64/libvulkan1/filelist

Which makes more sense.

Would be nice if you add an additional vulkan-devel package that has a required dependency for vulkan-headers and only adds pkg-config there

Additional info:
* package version(s): all
* config and/or log files etc.: none
* link to upstream bug report, if any: none

Steps to reproduce:
Use pkg-config with cmake (custom find_package), or just think about it.
