Builded 2.83a -> no GPU support


i build today 2.83a (First time i builded blender). First i tried to compile it with install_deps, but that failed with “OpenShadingLanguage-1.10.9 failed to compile, exiting”, that i cant slove. So i used the precompiled libraries and build blender. But it cant find my GPU anymore. 2.82.7 download does work with my GTX1660.

How do a build with GPU support?

My system:

Linux leatsink 4.15.0-72-generic #81-Ubuntu SMP Tue Nov 26 12:20:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

System Info from my build:


CPU device capabilities: SSE2 SSE3 SSE41

OpenCL device capabilities:
No OpenCL platforms found

There are some errors if i start my build version, i loaded my preference file from 2.82.7:

Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control).  Otherwise reinstall numpy.

Original error was: cannot import name 'multiarray' from 'numpy.core' (/home/re/blender-git/build_linux/bin/2.83/python/lib/python3.7/dist-packages/numpy/core/
