There is another reference to CXX generating warnings to project without using CXX. https://github.com/ROCm/clr/blob/2adcc33bedfba3123b86d3cd7d769d86d342b0e2/hipamd/hip-config-amd.cmake#L62 It seems that

-- Check for working HIP compiler: /opt/rocm-6.0.0/llvm/bin/clang++ - skipped

The HIP compiler has been found above, I don't get why looking for HIP_CXX_COMPILER compiler via CMAKE_CXX_COMPILER. I would expect no warning.

Operating System

Steps to Reproduce

CMakeLists.txt

cmake_minimum_required(VERSION 3.21 FATAL_ERROR)
project(qe LANGUAGES Fortran C HIP)
find_package(hip CONFIG)

command:

cmake -DCMAKE_C_COMPILER=gcc -DCMAKE_Fortran_COMPILER=gfortran .

Need patch first if testing with rocm 6.0.0 release

I think this is fixed by this older commit https://github.com/ROCm/clr/commit/515d07cb3ab7b2f206cfded0c7f288e01a0282f1 that is not yet into release. Could you please confirm.
