Run libtorch examples, export error "undefined reference to xxx" #73829
Description
🐛 Describe the bug
When run the pytorch example: https://pytorch.org/cppdocs/installing.html

cpp:
#include <torch/torch.h>

int main() {
torch::Tensor tensor = torch::rand({2, 3});
std::cout << tensor << std::endl;
}
cmake command:
cmake -DCMAKE_PREFIX_PATH=/home/guangtong/project/libtorch ..
cmake --build . --config Release
will appears:
