Build fails on multiple versions on Pop_OS!

Trying to run the example from the README and getting these errors:

error[E0308]: mismatched types

Same things happens on version 0.10.3.

Tried using the repo as the source, get even more errors:

Cloned the repo, fixed the previously mentioned missing Option errors and this is what remains:

    | ^^^^^^^^^^^^^^^^^^^^^^

Also tried to run the capture example but needless to say, it also did not work.

Here are my specs for my system:

OS: Pop!_OS 22.04 LTS x86_64 
CPU: Intel i5-9400H (8) @ 4.300GHz 
GPU: NVIDIA Quadro T1000 Mobile 
GPU: Intel CoffeeLake-H GT2 [UHD Graphics 630] 
Memory: 8GB 

As an additional troubleshooting step, I even reverted the main.rs file to a simple "Hello World!" and it still, the same errors appears. It simply won't compile.

Am I doing something wrong? Am I missing any dependencies?

Also getting this issue, would love to know if there's a workaround or solution

I've had the same issue on Fedora 39. I got around it by just having a local copy of this commit as stated here: https://github.com/l1npengtul/nokhwa/issues/147#issuecomment-1964927366.
