CXX ver for LibTorch versions

I am working on ROS Noetic C++ package, which uses libtorch, but I can’t even build it.
I think problem in mismatches between libtorch CXX versions and other ROS libraries, which are compiles only when 11 is on. Is there some documentation where I can check which CXX is used by libtorch versions?
Many thanks!

The current main branch needs a compiler supporting C++17 as seen here.
