NOT FOUND. GVDB Ptx/Glsl. (ptx or glsl missing)

I'm running a project one which needs gvdblibrary and contains a gPointCloud file that was modified from the gPointCloud in version 1.1 of GVDB voxels(but now i just can use version 1.1.1of gvdblibrary) In the process of building that project,I encountered the following error report

robot@WP:/usr/local/MPM3D/MPM/gPointCloud/build$ cmake -DGVDB_ROOT_DIR="/home/robot/nvidia/gvdb-voxels/_output/" .. CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required): Compatibility with CMake < 2.8.12 will be removed from a future version of CMake.

Update the VERSION argument value or use a ... suffix to tell CMake that the project does not need compatibility with older versions.

I have seen the cuda 10.2 build error#106 and I did the same operation with him which is that"after copying files from bin folder to lib https://github.com/NVIDIA/gvdb-voxels/issues/106 I don't know the difference between us.His results show that "Found. GVDB Ptx/Glsl. " I promise that my lib files contains the 5 .glsl files and 2.ptx file which is in his result.

Is this caused by the version 1.1.1 of gvdb voxels different from version1.1?I can't understand . Hope you can guide me ,thank you very much.
