Subject: cuda: Add cublasLt_static linking when GGML_STATIC is enabled (#15622)
X-Git-Tag: upstream/0.0.6527~224
X-Git-Url: https://git.djapps.eu/?a=commitdiff_plain;h=5a0e3ef6f00c658fbae53797f02d5a360ebf8fec;p=pkg%2Fggml%2Fsources%2Fllama.cpp

cuda: Add cublasLt_static linking when GGML_STATIC is enabled (#15622)

Prior to this change, we faced undefined cublasLt references when
attempting to compile 'llama-cli' with GGML_STATIC=ON on Linux.

We add linking with CUDA::cublasLt_static when CUDA version is greater
than 10.1.
