|
----------
|
|
|
|
|
|
|
|
|
|
Find Vulkan, which isis a low-overhead, cross-platform 3D graphics
|
|
|
|
|
and computing API.

IMPORTED Targets
|
|
|
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
This module defines :prop_tgt:`IMPORTED` target ``Vulkan::Vulkan``, if
|
|
|
|
|
Vulkan has been found.
|
|
|
|
|
|
|
|
|
|
Result Variables
|
|
|
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
This module defines the following variables::
|
|
|
|
|
|
|
|
|
|
Vulkan_FOUND - "True" if Vulkan was found
|
|
|
|
|
Vulkan_INCLUDE_DIRS - include directories for Vulkan
|
|
|
|
|
Vulkan_LIBRARIES - link against this library to use Vulkan
|
|
|
|
|
|
|
|
|
|
The module will also define two cache variables::
|
|
|
|
|
|
|
|
|
|
Vulkan_INCLUDE_DIR - the Vulkan include directory
|
|
|
|
|
Vulkan_LIBRARY - the path to the Vulkan library
|
|
|
|
|
|
|
|
