Linking error with whisper-rs when using vulkan: multiple definitions of symbol

[FireFragment]

When using the vulkan feature on both llama_cpp and whisper-rs from the same crate, build fails with many error messages similiar to this one:

/bin/ld: /home/user/Programming/Rust/tests/problem_isolation/vulkan-ai/target/debug/deps/libllama_cpp_sys-6172acf8774b4f66.rlib(3487caebe0aa41d4-ggml-vulkan.o):/home/user/.cargo/registry/src/index.crates.io-6f17d22bba15001f/llama_cpp_sys-0.3.2/./thirdparty/llama.cpp/ggml-vulkan-shaders.hpp:69574: multiple definition of `sqr_f32_data'; /home/user/Programming/Rust/tests/problem_isolation/vulkan-ai/target/debug/deps/libwhisper_rs_sys-a2fb035baa881db4.rlib(ggml-vulkan-shaders.cpp.o):/home/user/Programming/Rust/tests/problem_isolation/vulkan-ai/target/debug/build/whisper-rs-sys-ea85f180824249f0/out/build/ggml/src/ggml-vulkan-shaders.cpp:126068: first defined here
collect2: error: ld returned 1 exit status

Note: See also similar issue I've made in whisper-rs repo: tazz4843/whisper-rs#194

To reproduce

Beware, that just creating a crate with dependencies on llama_cpp and whisper-rs with vulkan features isn't enough to reproduce this error, because (I guess) rust compiler optimizes the linking away so you need to actually use both crates in the code.

I have made a simple crate to reproduce this error. Build it with

git clone https://github.com/FireFragment/vulkan-ai-linkage-error
cd vulkan-ai-linkage-error
cargo b

If you use Nix, you can reproduce the full environment I got the build failure with

git clone https://github.com/FireFragment/vulkan-ai-linkage-error
cd vulkan-ai-linkage-error
nix develop -c cargo b
