Hi guys,

I want to create a new system image with a package inside. I am doing it by:

```julia
julia build_sysimg.jl /tmp/test core2 userimg.jl 

```

in which `userimg.jl` has only `using SatelliteToolbox`.

After the end of the process, I start Julia using `julia -J /tmp/test` but `using SatelliteToolbox` fails with:

```julia
ERROR: ArgumentError: Package SatelliteToolbox not found in current path:
- Run `Pkg.add("SatelliteToolbox")` to install the SatelliteToolbox package.

Stacktrace:
 [1] require(::Module, ::Symbol) at ./loading.jl:817

```

How can I do this?

Btw, I can access the functions using `SatelliteToolbox.`.

I am starting to think this is a bug. The package and its dependencies are indeed included, but I cannot export the symbols with `using`.
