Feature Request: Support vulkan when building on Android

[XinyuGroceryStore]

Prerequisites

• I am running the latest code. Mention the version if possible as well.
• I carefully followed the README.md.
• I searched using keywords relevant to my issue to make sure that I am creating a new issue that is not already open (or closed).
• I reviewed the Discussions, and have a new and useful enhancement to share.

Feature Description

What I have done

I have succeeded in building project on Win laptop by following "Build on Android" and running it with Android Debug Bridge.
I also succeeded in building project on Win by running cmake -B build -DGGML_VULKAN=ON cmake --build build --config Release on cmd and running examples on my Win laptop with Nvidia GPU recognized.

Problem I meet

Then I try running on Win cmd:

set NDK=C:/Path/to/AppData/Local/Android/Sdk/ndk/27.0.12077973
set VULKAN_SDK=C:/VulkanSDK/1.3.283.0
cmake -G "Ninja" ^
    -DCMAKE_TOOLCHAIN_FILE=%NDK%/build/cmake/android.toolchain.cmake ^
    -DANDROID_ABI=x86_64 ^
    -DANDROID_PLATFORM=android-23 ^
    -DCMAKE_C_FLAGS=-march=x86-64 ^
    -DGGML_VULKAN=1 ^
    -DVulkan_INCLUDE_DIR=%VULKAN_SDK%/include ^
    -DVulkan_LIBRARY=%VULKAN_SDK%/Lib/vulkan-1.lib ..

Project was built.

However when I ran `ninja`, error happens:   ### What I expect I hope to build binary files with Vulkan support that can run on my Android device.

Motivation

Some Android Devices support vulkan for rendering. And Llama.cpp supports vulkan for inference accelaration as well. If project with vulkan support that can run on Android devices can be built, it will be much better to deploy LLMs locally on edge devices.

Possible Implementation

No response
