ArrayFire's CUDA backend linked against the CUDA numeric libraries
staticly before this change. This caused the libafcuda library to be
in the 1.1GB range for CUDA 11.5 even if you were targeting one compute
capability. This is partially due to the fact that the linker does not
remove the compute capabilities of older architectures when linking.
One way around this would be to use nvprune to remove the architectures
that are not being used by the compute cability when building. This
approach is not yet implemented.
This commit will revert back to dynamically linking the CUDA numeric
libraries by default. You can still select the old behavior by setting
the AF_WITH_STATIC_CUDA_NUMERIC_LIBS option in CMake
