## To Reproduce

1. ArchLinux
2. Python 3.10 (sic)
4. git master
5. gcc 13.2.1

submodules initiated

Commencez par reproduire l’échec de compilation d’ArchLinux et inspectez src/opentimelineio/any.h, qui inclut any/any.hpp, ainsi que la configuration des dépendances et de la compilation du dépôt. Confirmez comment la dépendance any.hpp est censée être fournie, puis vérifiez qu’une compilation propre s’achève sans les erreurs liées aux en-têtes manquants.
