Apparently, we have:
https://cmake.org/cmake/help/latest/prop_gbl/CMAKE_CXX_KNOWN_FEATURES.html
and
https://cmake.org/cmake/help/latest/prop_gbl/CMAKE_CUDA_KNOWN_FEATURES.html
but there is no equivalent for HIP.
Is this an oversight? It seems unfortunate to have HIP be a language in CMake but not actually have that support be full-featured, as C++ standards are something that HIP users need just as much as CUDA.
Thanks.
