%description
This project provides the Khronos official Vulkan ICD desktop 
loader for Windows, Linux, and MacOS.

%package -n %{libname}
Summary:	Vulkan ICD loader library
Group:		System/Libraries
Requires:	%{name} = %{EVRD}

%description -n %{libname}
The Vulkan ICD loader library.

Vulkan is an explicit API, enabling direct control over how GPUs actually work.
As such, Vulkan supports systems that have multiple GPUs, each running with a
different driver, or ICD (Installable Client Driver).

Vulkan also supports multiple global contexts (instances, in Vulkan
terminology). The ICD loader is a library that is placed between a Vulkan
application and any number of Vulkan drivers, in order to support multiple
drivers and the instance-level functionality that works across these drivers.
Additionally, the loader manages inserting Vulkan layer libraries, such as
validation layers, between an application and the drivers.

%package -n %{devname}
Summary:	Development files for %{name}
Requires:	%{libname}%{?_isa} = %{version}-%{release}
Requires:	vulkan-headers >= %{version}
Provides:	vulkan-devel = %{EVRD}

%description -n %{devname}
The %{name}-devel package contains libraries and header files for
developing applications that use %{name}.
