Build libtorch1.10.2(c++) from source doesn't generate libtorch_cuda.so

C++
1

I build the libtorch1.10.2 by following command

git clone --recurse-submodules -j6 https://github.com/pytorch/pytorch.git -b v1.10.2
cd pytorch/tools/
mkdir build
cd build
 python3 ../tools/build_libtorch.py

after finishing the build successfully, so file related cuda was missing
ex)

  libtorch_cuda.so
  libc10_cuda.so
  libcaffe2_detectron_ops_gpu.so

btw I could generate those so file with libtorch1.7 and libtorch1.9 with no problem

Do you have any idea why it didn’t generate libtorch_cuda.so file with libtorch1.10.2

I use

GPU RTX2060 
NVIDIA Driver 470.57.02
CUDA11.0
