CrowPanel 7.0": CrowPanel_ESP32_LVGL_Demo.ino:117: undefined reference to `lv_demo_widgets'

Hello,
I am facing a build error with CrowPanel_ESP32_LVGL_Demo.ino from Lesson 5 LVGL Demo Test.

• lvgl version 8.3.11
• LovyanGFX version 1.1.16

I copied the 2 demoset examples folders from the lvgl directory to my sketch directory but:

undefined reference to `lv_demo_widgets'
collect2.exe: error: ld returned 1 exit status

Do you know how to fix this?
