Problem Building With 2.5.43 on PlatformIO

[niveus]

Hello. I'm trying to build using PlatformIO and I get an error if I try to enable the -DSMOOTH_FONT=1 flag. It's looking for SPIFFS.h (which is in the platform path) and not finding it. The library builds fine if I don't use the smooth font flag.

My ini:

[platformio]
default_envs = unexpected

[env]
platform = espressif32
framework = arduino
monitor_speed = 460800
lib_deps =

[env:unexpected]
board = um_pros3

and the error:

How do I get it to include the platform path (which I would have thought it already had)? Also, shouldn't it be #include <SPIFFS.h>?

Thanks
