Dear all,

When I try to import `CUDAnative` into Julia 1.6.3, I get the following error:

```julia
julia> import Pkg; Pkg.add("CUDAnative")
   Resolving package versions...
ERROR: Unsatisfiable requirements detected for package CUDAapi [3895d2a7]:
 CUDAapi [3895d2a7] log:

```

I work on an Asus Strix ROG laptop, with Nvidia GeForce RTX card. The laptop is running Ubuntu 20.04. I have installed CUDA 10.1 Toolkit prior to installing Julia, which I built from the sources on github. (I somehow believed that if I have CUDA during the Julia compilation, it (Julia) will be aware of CUDA, but I could be wrong, of course).

I believe that installation of CUDA 10.1 was successful (albeit a very frustrating task), since the command: `nvidia-smi` gives me the following output:

```julia

```

which should, to my limited experience, be an indication that CUDA is properly installed and that the OS is aware of CUDA libraries.

What could be going on here?

Cheers

CUDAnative.jl is deprecated, use CUDA.jl.
