Godot editor on android doesn't copy over dependencies whent they're located on sdcard.

[lemonJumps]

Tested versions

• Tested in: 4.2.1

Most likely occurs in all versions due to dependencies not being touched by the code that loads a library.

System information

Godot v4.2.1stable - Android - Vulcan (Mobile) - integrated Adreno (TM) 619 - (8 Threads)

Issue description

When opening a project with gdextension in the android editor, that is located on an sdcard, the gdextension file is copied over into a cache, however other dependencies are not copied over, causing the library to not load.

Steps to reproduce

Have a single project with one GDExtenension library, and another library that is its dependency next to it, and a Gdextension file that has both library and dependency describet inside of it.

With this project placed onto an android phone, opening it will cause the error.

Minimal reproduction project (MRP)

Here's a minimal project, (I've used the library which I'm currently using and is causing the issue, but it's in total over 10 MB): https://github.com/lemonJumps/gdextension-bug

@lemonJumps Can you update the minimal project and make the shared library use a relative path when loading its dependencies; for example dlopen("./libopencv_calib3d.so", ...) instead of dlopen("libopencv_calib3d.so", ...)

The app is unable to update the LD_LIBRARY_PATH path on Android, which prevents your shared library from finding its dependencies after they are copied.

@lemonJumps I've added a draft PR in #88381. Once you're able to update your MRP, I can validate that it works as expected.

I know it's not an MRP, but https://github.com/alessandrofama/fmod-for-godot also suffers from this issue and could be used in testing. (It's the one that made me search out and try to find this!)

Thanks @BSChad! Do you see any specific errors when trying to use the the fmod plugin besides not loading?

Nope. The error is that it can't find libfmod, which is the compiled library that the extension library is trying to load.

@BSChad I've tested with the changes from the PR, and the plugin now loads fine!
