Is your feature request related to a problem? Please describe.

My application is able to dynamically load dependencies using dlopen + dladdr.
I have modeled every library using prefab json files.

But I don't know of any way, other then explicitly do target_link_libraries to add a dynamic dependency to the .apk.

Describe the solution you'd like

I have 2 suggestions:

1. add every dependency of the target to the .apk.
   Doing add_dependencies(myexecutable dynamic_dependency), should add dynamic_dependency to the .apk as well
2. add some function to the android cmake toolchain script that marks a target to be added to the .apk:
   add_target_to_apk(dynamic_dependency)

Describe alternatives you've considered

Right now, I'm simply doing

target_link_libraries(mygame PRIVATE dynamic_dependency)

This type of dependency is honored by android's cmake support,
but should not be necessary.

Additional context

I have encountered this issue while creating a prefab aar for SDL_image.
SDL_image provides decoders for various image formats.
Because not every applications needs every decoder, these are dynamically loaded.
Dynamically loading also reduces the file size of an .apk.
