When I building from source on ubuntu 20.04

cmake version

$ cmake --version
cmake version 3.16.3

CMake suite maintained and supported by Kitware (kitware.com/cmake).

install opencl

$ apt-get install ocl-icd-*
$ apt-get install opencl-headers
$ apt-get install clinfo

build source

$ git clone -b gltfpack https://github.com/zeux/basis_universal
$ cd basis_universal

What can I do this error make: *** No rule to make target 'gltfpack'. Stop.？

This is because you're running cmake & make from basisu_universal folder - instead, it should be ran from meshoptimizer folder.

The build instructions here https://github.com/zeux/meshoptimizer/tree/master/gltf#building should work I believe.
