build and ggml_print_backtrace issue #3204
Description
I am encountering linker errors when building the project using Visual Studio 2022 on Windows. The errors are:
text
Error LNK2019: unresolved external symbol ggml_print_backtrace referenced in function ggml_uncaught_exception
Error LNK1120: 1 unresolved externals
Steps to reproduce:
Clone the repository fresh.
Configure the build with CMake (e.g., cmake -B build -DGGML_CUDA=1).
Open the generated .sln file.
These are my terminal screenshots

Could you please advise if this is a known issue or if there is a recommended fix/workaround? Is there a missing source file or a CMake configuration adjustment needed to properly include the implementation of ggml_print_backtrace?
