When compiling CUDA files with nvcc (CUDA 11.3 and GCC 9.4), when including catch2 and declaring a simple test case, I'm getting warnings such as variable "[...]autoRegistrar1" was declared but never referenced.
Is there a way to get rid of these warnings?

Platform information:

  • OS: Linux x86_64
  • Compiler+version: NVCC 11.3 / GCC 9.4.0
  • Catch version: v2.13.0 [included as part of CMake build, with cmake 3.17.0]

Other issues similar to this have been opened (#2132, #1552) but I believe they're not using a fairly recent GCC.
