I want Use Libtorch in Champsim Simulator，but when I execute “make”，I got：

I try Using Libtorch in Champsim, I change the makefile as follows:
CXXFLAGS := -I/home/tx/software/libtorch/include/torch/csrc/api/include -L/home/tx/software/libtorch/lib/
CXXFLAGS += -I/home/tx/software/libtorch/include/
CXXFLAGS += -lbackend_with_compiler
CXXFLAGS += -lc10
CXXFLAGS += -lc10_cuda
CXXFLAGS += -lc10d_cuda_test
CXXFLAGS += -lcaffe2_nvrtc
CXXFLAGS += -ljitbackend_test
CXXFLAGS += -lnnapi_backend
CXXFLAGS += -lshm

LDLIBS := -L/home/tx/software/libtorch/lib/
I set the right libtorch path,which is from pytorch.org,I also tried compile from source code of pytorch, but I got the same error Does anyone can help me？
