This will test linking hip::device interface in cmake

I. Build

mkdir -p build; cd build
rm -rf *;
CXX="$(hipconfig -l)"/clang++ cmake -DCMAKE_PREFIX_PATH=/opt/rocm ..
make

Note, users may need to add ADMGPU support as command line option, if test failed to run, for example,

CXX="$(hipconfig -l)"/clang++ cmake -DCMAKE_PREFIX_PATH=/opt/rocm -DAMDGPU_TARGETS="gfx1102" ..

To enable compiler auto detection of gpu users may need to add ADMGPU support as command line option, if test failed to run, for example,

CXX="$(hipconfig -l)"/clang++ cmake -DCMAKE_PREFIX_PATH=/opt/rocm -DAMDGPU_TARGETS=native ..

II. Test
