[Fastfetch] Replace hard coded paths

[CarterLi]

Describe the bug

Fastfetch uses hwdata/pci.ids and libdrm/amdgpu.ids to convert PCI device ID to human-readable product name.

Currently their paths are hard coded as /usr/share/hwdata/pci.ids and /usr/share/libdrm/amdgpu.ids. It won't work with NixOS of course.

https://github.com/fastfetch-cli/fastfetch/blob/dev/src/detection/gpu/gpu_linux.c#L126-L137

I found some packages that have similar issues. They are patched directly before building:

nixpkgs/pkgs/tools/graphics/mangohud/hardcode-dependencies.patch

Line 38 in 662ae2a

- file.open("/usr/share/hwdata/pci.ids");

Fastfetch needs to be patched too.

Expected behavior

Fastfetch can properly find pci.ids and amdgpu.ids

Additional context

Reference: fastfetch-cli/fastfetch#855

Fastfetch provided cmake config option CUSTOM_PCI_IDS_PATH for pci.ids but not for amdgpu.ids. I can add one if needed.

Hi thanks for the detailed issue report!
This should be pretty straightforward to fix. If you could add a config option for the amdgpu.ids path that would be great! Many thanks.

Done.

cmake -DCUSTOM_PCI_IDS_PATH=/path/to/pci.ids -DCUSTOM_AMDGPU_IDS_PATH=/path/to/amdgpu.ids
