Automatic SDL2 build fails on windows with bundled feature

[creikey]

The error:

thread 'main' panicked at 'Failed to copy SDL2 dynamic library from C:\Users\camer\Documents\Tech\explain\target\debug\build\sdl2-sys-6797cdb03e082686\out\bin\SDL2.dll to C:\Users\camer\Documents\Tech\explain\target\debug\SDL2.dll: Os { code: 2, kind: NotFound, message: "The system cannot find the file specified." }', C:\Users\camer\.cargo\registry\src\github.com-1ecc6299db9ec823\sdl2-sys-0.34.4\build.rs:592

sdl2 = { version = "0.34.4", features = ["bundled"]

FYI I got linking to work correctly, with CI testing, in PR #1092

What is concerning however is that while the static-link version of "bundled" passes tests 100%, the following happens on the dynamic link version:

 failures:
    src/sdl2\event.rs - event::EventSender::push_custom_event (line 2874)
    src/sdl2\event.rs - event::crate::EventSubsystem::add_event_watch (line 244)
    src/sdl2\event.rs - event::crate::EventSubsystem::push_custom_event (line 203)
    src/sdl2\event.rs - event::crate::EventSubsystem::register_event (line 135)
    src/sdl2\rect.rs - rect::Rect::has_intersection (line 482)
    src/sdl2\rect.rs - rect::Rect::intersection (line 504)
    src/sdl2\rect.rs - rect::Rect::union (line 536)

test result: FAILED. 62 passed; 7 failed; 0 ignored; 0 measured; 0 filtered out; finished in 12.63s

Given that most of the tests are passing, but some are failing, something is subtly wrong with this version of the build. My first guess is that there is an ABI difference that isn't getting picked up one one side of the build.

Ah, these are the examples that actually invoke code in sdl2 thus need the runtime linking.
