Setting up LVGL: fsl_cache.h not found

Hi everyone, i previously post a thread asking for help setting up the TFT_eSPI library to be able to use the LVGL library. I set it up correctly and now it is perfectly working. So I moved to the LVGL. After fallowing the simple steps for the set up that you can se here i tried to compile and load on my T4.1 the example LVGL_Arduino. Later i will download the lv_example library and try that one too. The problem is that it doesn't even compile because "fsl_cache.h" is not found on ...Documents\Arduino\libraries\lvgl\src\draw\nxp\pxp/lv_gpu_nxp_pxp.h . I took a look at lv_gpu_nxp_pxp.h and here's what I found:

Code: 
#include "../../../lv_conf_internal.h"

#if LV_USE_GPU_NXP_PXP
#include "fsl_cache.h"
#include "fsl_pxp.h"

#include "../../../misc/lv_log.h"

So it includes fls_cache.h only if LV_USE_GPU_NXP_PXP is set. That is on User_setup.h, as you can see below.

Code: 
/*Use NXP's PXP GPU iMX RTxxx platforms*/
#define LV_USE_GPU_NXP_PXP 1
#if LV_USE_GPU_NXP_PXP
    /*1: Add default bare metal and FreeRTOS interrupt handling routines for PXP (lv_gpu_nxp_pxp_osa.c)
    *   and call lv_gpu_nxp_pxp_init() automatically during lv_init(). Note that symbol SDK_OS_FREE_RTOS
    *   has to be defined in order to use FreeRTOS OSA, otherwise bare-metal implementation is selected.
    *0: lv_gpu_nxp_pxp_init() has to be called manually before lv_init()
    */
    #define LV_USE_GPU_NXP_PXP_AUTO_INIT 0
#endif

I'll be onest, i don't quite cach what it does (so big thank you if you can explain it to me), but seems to me that i can choose to set LV_USE_GPU_NXP_PXP or not. In fact, if I set it to 0, i don't get the fsl_cache.h error, but instead i get this:

Errore durante la compilazione per la scheda Teensy 4.1.

Did anyone had the same problem? Can you help me figure it out?

Thaks to anyone made it 'till here, and to who didn't
 
I played around with it for a bit and it doesn't look like there is going to be an easy fix. On the LVGL page I found the instructions for setting it up and they use the drivers from NXP's SDK. The big problem is that they appear to have a whole pile of dependencies from the SDK so you ca't just copy and paste in the drivers. I guess I will have to try out NXP's ide to get the PXP accelerated graphics to work.
