trying with hipsycl

hipsycl@develop + gcc%11:
or hipsycl-0.9.3 + gcc%10.2
or [email protected] + gcc%12.2 + llvm 15.0.7:

     clang-16: error: cannot find libdevice for sm_86; provide path to different CUDA installation via '--cuda-path', or pass '-nocudalib' to build without linking with libdevice

hipsycl@develop + gcc%12.2 + llvm 16
(or [email protected] + gcc%12.2 + llvm 15???):

        /opt/software/gcc/12.2.0/lib/gcc/x86_64-pc-linux-gnu/12.2.0/../../../gcc/x86_64-pc-linux-gnu/12.2.0/include/c++/bits/shared_ptr_base.h:196:22: error: use of undeclared identifier 'noinline'; did you mean 'inline'?
        __attribute__((__noinline__))

llvm 14 is not compiling with gcc 12.2
hipsycl-0.9.2 is incompatible with llvm 15
