HIP: INTERFACE_INCLUDE_PATH not proppagated

Using CMake 3.21.4 and ROCM 4.5 https://github.com/ye-luo/cmake_gpu/tree/master/test_rocm mkdir build; cd build; cmake .. runs fine.

... # I print INTERFACE_INCLUDE_PATH in the CMakeLists.txt
hipblas INTERFACE_INCLUDE_PATH = /opt/rocm-4.5.0/include
...

When I dug into the generated files

$ grep INCL CMakeFiles/foo.dir/flags.make 
HIP_INCLUDES = 

It is empty. A following make succeeded but it was correct because of special treatment in the ROCM shipped compiler I guess. The cause of empty HIP_INCLUDES is

set_source_files_properties(foo.hip.cpp PROPERTIES LANGUAGE HIP)

The reason I declare this file as HIP because in my full application, it would contain HIP kernel source codes. For this reason, I'm wondering why INTERFACE_INCLUDE_PATH was not propagated and how to get this fixed.
