   The `glob.cpp` file includes the file `xtensa-esp32-elf/sys-include/dirent.h`, which includes `xtensa-esp32-elf/sys-include/sys/dirent.h`, which causes this error. This is because the filesystem related functions are defined in the ESP-IDF repository (in `components/vfs/`). The `vfs/include/sys/dirent.h` header must therefore be included in `glob.cpp:135` instead of `<dirent.h>`:
