Standalone Windows error LNK2001: unresolved external symbol `__imp___tls_index_` and `__imp___tls_offset_`

Hi,

I'm building the MSVC project using CMake, but the linker cannot find the symbols __imp___tls_index_ and __imp___tls_offset_.

This seems to be the same issue as @acids-ircam/nn_tilde.

Thanks, Alex

Seems like an issue with libtorch. I was able to complete the build using the workaround here: https://stackoverflow.com/a/74437172/8232122.
