Hardware acceleration support for Blender is enabled if a CUDA toolkit
is detected when Blender is being built. The CUDA toolkit is no longer
required after Blender has been built; it is only required during
building.

The CUDA toolkit SlackBuilds which have been tested and are known to
work are:
    development/cudatoolkit_12
    development/cudatoolkit_13.

The main difference between the toolkits is the collection of compute
capabilities that each one supports. This, in turn, determines the
graphics cards able to be supported by the final Blender package.
The relationship between compute capability and various graphics cards
can be seen at:
    https://developer.nvidia.com/cuda/gpus
and
	https://developer.nvidia.com/cuda/gpus/legacy

With one of the CUDA toolkits installed, the range of supported
architectures can be displayed by executing the command:
    nvcc --list-gpu-arch

The range of architectures (hence compute capabilities) supported by
Blender itself may not support all those that are supported by a
particular version toolkit.

For instance, when building blender-5.1.2 with cudatoolkit_13, terminal
output will show lines like:
    CUDA binaries for sm_50 are no longer supported with CUDA 13.0+

with similar lines for sm_52, sm_60, sm_61 and sm_70.

This means that compute capabilities (CC's) 5.0, 5.2, 6.0, 6.1 and 7.0
are not suppported. If your graphics card happens to fall into this
category, build Blender with cudatoolkit_12 which still supports these
older architectures.
