Cross-posted on [PackageCompiler.jl](https://github.com/JuliaLang/PackageCompiler.jl/issues/933).

I’m building binaries with `PackageCompiler.create_app()`, but I get an alarming warning message whenever a dependency has an `__init()__` function that includes a `@require` block, exemplified by the following packages:

- [JLD2.jl](https://github.com/JuliaIO/JLD2.jl/blob/master/src/JLD2.jl#L640)
- [HDF5.jl](https://github.com/JuliaIO/HDF5.jl/blob/master/src/HDF5.jl#L121)

If I include these dependencies in my package, I get some alarming warning messages (although the app runs fine)

```

Is there anyway to suppress this warning message?

I came across [this post](https://discourse.julialang.org/t/zygote-jl-and-packagecompiler-jl/35839) which seem to suggest any package that uses `Requires.@require` cannot be compiled into an app (as of 2020). Then I saw [this issue](https://github.com/JuliaIO/HDF5.jl/pull/891) in 2022 which seems to have fixed this problem, but apparently not for my case.

Ultimately I created my own forks of these packages and commented out all the `Requires.@require` statements (adding/removing dependencies as needed) for my specific application to work.

Did you create bug reports for the packages you had to fork?
