Nvlink fatal : Could not open input file '/usr/lib/x86_64-linux-gnu/librt.a'

Accelerated Computing CUDA CUDA NVCC Compiler

Hi,
I was compiling dcn_v2 code from GitHub - smallsunsun1/custom_ops: Deformable Convolution Networks(deformable conv2D TF_implementation) , but ran into following error:

nvlink fatal   : Could not open input file '/usr/lib/x86_64-linux-gnu/librt.a'
make[2]: *** [CMakeFiles/ops.dir/build.make:132: CMakeFiles/ops.dir/cmake_device_link.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:83: CMakeFiles/ops.dir/all] Error 2
make: *** [Makefile:91: all] Error 2

I’m using gcc 9.4.0 and tensorflow 2.8.0.

Here, is my cmake file:
