ArrayFire and FFTW dependency Issue

Hello,
I’ve been trying to install ArrayFire but there seems to be some issue regarding dependencies regarding
FFTW (and Zygote).
Here with the most recent FFTW@1.2.0:

ERROR: Unsatisfiable requirements detected for package ArrayFire [b19378d9]:
 ArrayFire [b19378d9] log:
 ├─possible versions are: [0.7.0, 1.0.0-1.0.4] or uninstalled
 ├─restricted to versions * by an explicit requirement, leaving only versions [0.7.0, 1.0.0-1.0.4]
 └─restricted by compatibility requirements with FFTW [7a1cc6ca] to versions: uninstalled — no versions left
   └─FFTW [7a1cc6ca] log:

     └─restricted to versions 1.2.0 by an explicit requirement, leaving only versions 1.2.0

I tried to downgrade to FFTW@1.0.0 but i get the same result.
Downgrading further seems to break things with Zygote:

(v1.3) pkg> add FFTW@0.3.0

I would open an issue on the github page but i am not really sure about which one: ArrayFire or FFTW?
Or maybe this is not even an issue and I am doing something wrong.
