CMake can NOT find Vulkan when building

[PerssonBrown]

OS: Windows 11
Qt version: 6.6.1

CMake always reports missing: Vulkan_INCLUDE_DIR, like this:

This project is generated with a template(Qt Widgets Application) in Qt Creator, and I didn't modify any files.

Here are my questions:

• What is Vulkan?
• Do all Widget Applications need Vulkan?
• How to fix this missing warning?

I am new in QT, please be nice to me :)

@PerssonBrown Vulcan is a 3D graphics API, see https://en.wikipedia.org/wiki/Vulkan
On Windows you can ignore this, Qt is using DirectX or OpenGL on Windows.

@PerssonBrown said in CMake can NOT find Vulkan when building:

Here are my questions:

• What is Vulkan?

It is a library for displaying graphics, much like OpenGL, DirectX or Metal.

• Do all Widget Applications need Vulkan?

No, you can safely ignore this warning. When Vulkan is not present, Qt will use other libraries to draw stuff.

• How to fix this missing warning?

On Windows I'm not sure if you can fix it, but you can ignore it.
