Build failed when use shared MKL library #138994
Description
Which version of oneAPI are you using to build pytorch? I am using oneAPI binaries from https://www.intel.com/content/www/us/en/developer/articles/tool/pytorch-prerequisites-for-intel-gpu/2-5.html and I am getting linking errors:
Creating library lib\torch_cpu.lib and object lib\torch_cpu.exp

bin\torch_cpu.dll : fatal error LNK1120: 4 unresolved externals
Looking at CMakeFiles/torch_cpu.rsp I see that mkl_core_dll.lib is used for linking and it doesn't define these i_* symbols.
