Missing SYCL functions in final linking stage of rxmd build

[TaufeqRazakh]

For PR #51 when building with the following command

cmake -DCMAKE_CXX_COMPILER=icpx -DTorch_DIR=/soft/datascience/aurora_models_frameworks-2023.2/lib/python3.9/site-packages/torch/share/cmake/Torch/ -DIPEX_DIR=/soft/datascience/aurora_models_frameworks-2023.2/lib/python3.9/site-packages/intel_extension_for_pytorch/share/cmake/IPEX/ -DCMAKE_Fortran_COMPILER=mpif90 -DRXMD_ENABLE_TORCH=ON -DRXMD_ENABLE_IPEX=ON ..

An issue arises in final stage of linking:

I have tried adding SYCL link directories to both rxmd and torch_rxmd targets separately, but the issue still prevails.
