Research direction

Start by reproducing the minimal C++ application build with the nightly libtorch package and inspect the linker command for CMakeFiles/mymodel.dir/all. Review the supplied libtorch.so references and the reported entry point; done means the application links without these errors.

Description

Hi there,
