whl contains .cpp files

whl package contains .cpp files in pytorch/csrc. Is that code need compile on target machine?

/usr/local/lib/python3.12/dist-packages/transformer_engine# ls pytorch/csrc/extensions/
activation.cpp  attention.cu  cast.cpp               gemm.cpp  multi_tensor       nvshmem_comm.cpp  permutation.cu  quantizer.cpp  softmax.cpp  transpose.cpp
apply_rope.cpp  bias.cpp      comm_gemm_overlap.cpp  misc.cpp  normalization.cpp  padding.cpp       pybind.cpp      recipe.cpp     swizzle.cpp  type_converters.cpp

Start by examining the installed wheel contents under pytorch/csrc/extensions/ and tracing the project’s packaging entry points. Determine whether the .cpp files are required at runtime or were included unintentionally, then verify the expected wheel contents with a local build and inspection.
