If I bulid by cmake according to the lammps doc,

cmake -D PKG_GPU=on -D GPU_API=HIP -D HIP_ARCH=gfx906 -D CMAKE_CXX_COMPILER=hipcc …/camke is OK
When make -j 4, following error appeared.

The CMake configuration for the GPU package with GPU_API=hip needs updates. They are being worked on.
If you feel adventurous, you can download the latest LAMMPS development version via git clone from github.
It is probably better to stick with the conventional build procedure for now and just use the updated makefile.
