Error with `EVE` on ESP32 - undeclared defs.

[shymega]

Hi,

I'm converting a project that uses ESP-IDF to PlatformIO. I've locked the commits for lvgl/lvgl and this repo at the same hashes for lvgl/lv_port_esp32 - but I'm finding that I get these errors from the compiler:

It's seemingly related to EVE_config.h. I have the repo here, building with GitHub Actions on the fix-lvgl branch.

This code is a conversion from a proprietary GFX library to LVGL, and whilst it works fine on ESP-IDF from the company, the PlatformIO port, using known good commit hashes for the LVGL lib and LVGL ESP32 drivers, produces the above errors.

I'm not too clear if this repo is being maintained, there are a lot of open PRs, and I need to decide with the company I'm working with if we should continue to use LVGL.

If someone could help, that would be great!

Thanks.
