    OS: Windows 11
    Qt version: 6.6.1

    CMake always reports missing: Vulkan_INCLUDE_DIR, like this:

    0fee4915-5f7d-46aa-847a-c44a157643a0-image.png

    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.
