  I'm guessing this options.h and other files are from sdl2_mixer recipe which probably builds libtimidity, which have been extracted into the directory you are talking about. This is likely from the sdl2_mixer recipe or perhaps sdl2 recipe.

• "Unable to open main.py, abort." Error when running kivy app on iOS Simulator on xCode

  Long story short, there is not currently a recipe to cross-compile pandas for iOS. You can see the available recipes for iOS here or by issuing the command toolchain recipes

• Issue installing kivy_garden/zbarcam via toolchain

  Yeah according to this issue there is no recipe to cross-compile OpenCV to iOS. So to use zbarcam you probably would need to rectify that, plus the zbarcam recipe itself.

• Kivy app with pandas build in IOS
  2 projects | reddit.com/r/kivy | 19 Jun 2021

  An issue was raised with the same question here. Basically there is no "workaround", you need to make a recipe to cross-compile pandas for the target platform. You can see the existing recipes here: https://github.com/kivy/kivy-ios/tree/master/kivy_ios/recipes - you need to make "pandas" directory with code that accomplishes this ...
