NVML not found, disabling Nvidia GPU - NixOS

[BBFifield]

Describe the bug

Despite having Nvidia proprietary drivers installed on my NixOS system, NVML cannot be found when gBar is executed. The nvidia-smi command works fine, so I'm not quite sure why libnvidia-ml.so wouldn't be available.

Steps to Reproduce

1. Executed gBar bar HDMI-A-1 in alacritty
2. Nvidia stats weren't in the bar
3. Examined output in terminal and saw "NVML not found, disabling Nvidia GPU"

Expected behavior

gBar should have displayed my GPU stats
