libdrm required on nvidia-only build?

[yapolyak]

Hi,

I've been trying to build nvtop on a system with Nvidia-only GPU, and I could configure by running

cmake .. -DNVIDIA_SUPPORT=ON -DAMDGPU_SUPPORT=OFF -DINTEL_SUPPORT=OFF -DMSM_SUPPORT=OFF

as without the latter option it was complaining about the lack of libdrm which I don't seem to have installed, but nevertheless, when then running make, I am getting the header error:

.../nvtop/src/extract_gpuinfo_panfrost.c:24:10: fatal error: xf86drm.h: No such file or directory
   24 | #include <xf86drm.h>
      |          ^~~~~~~~~~~

So, is libdrm mandatory? If not, how to properly run configure?

I was using current master branch.

Thanks!
