When PyTorch is upgraded to version 2.7, the torch library is built with a new ABI, causing VPTQ to fail to compile successfully because it specifies the use of the old ABI. This PR detects the PyTorch version and conditionally adds the ABI flag to ensure compatibility with both older and newer versions of PyTorch.
This change prevents compilation failures when using PyTorch 2.7 while maintaining backward compatibility with earlier versions.
