.gdextension platforms questions

[asmaloney]

I can't find any detailed docs about the .gdextension file, so I'm not 100% clear what needs to be in here.

Right now I use the following in the libraries section which works for me so far on macOS:

linux.debug.x86_64 = lib/Linux-x86_64/lib${PROJECT_NAME}-d.so
linux.release.x86_64 = lib/Linux-x86_64/lib${PROJECT_NAME}.so
macos.debug.x86_64 = "lib/Darwin-x86_64/lib${PROJECT_NAME}-d.dylib"
macos.release.x86_64 = "lib/Darwin-x86_64/lib${PROJECT_NAME}.dylib"
windows.debug.x86_64 = "lib/Windows-AMD64/${PROJECT_NAME}-d.dll"
windows.release.x86_64 = "lib/Windows-AMD64/${PROJECT_NAME}.dll"

1. What is the list of acceptable platforms here?
2. If I have both debug and release as above, how does the engine choose which one to use? Is it dependant on the Godot build itself?

Here are the ones at the documentation:

[configuration]

entry_symbol = "example_library_init"
compatibility_minimum = "4.1"

[libraries]

macos.debug = "res://bin/libgdexample.macos.template_debug.framework"
macos.release = "res://bin/libgdexample.macos.template_release.framework"
windows.debug.x86_32 = "res://bin/libgdexample.windows.template_debug.x86_32.dll"
windows.release.x86_32 = "res://bin/libgdexample.windows.template_release.x86_32.dll"
