[LVGL] Includes added by LVGL_STYLES_DEF in the styles source file do not automatically match the changed header filenames

[tommikulevich]

Bug description

Last time I created a project in which I added prefix ui_ in the name of each file and change the templates in the "Settings -> Build -> Files" tab accordingly. After the generation of the code there was one include to the no longer existing file styles.h (should beui_styles.h) in ui_styles.c. Of course, I can change this manually, but I wanted to automate it and when generating a new UI not have to do it every time or create scripts.

To Reproduce

Steps to reproduce the behavior:

1. Create the new LVGL project, e.g. LVGL -> Scale
2. Go to 'Settings -> Build -> Files'
3. Add prefix ui_ to all file names except ui.h / ui.c, e.g. change styles.h to ui_styles.h
4. Change all file templates accordingly, e.g. change #include "vars.h" to #include "ui_vars.h" in ui_structs.h
5. Build the project
6. See wrong import #include "styles.h" in generated ui_styles.c

Expected behavior

Line #include "ui_styles.h" in generated ui_styles.c instead of #include "styles.h".

Wrong include after building:

Desktop:

• OS: Ubuntu Linux
• Version: 25.10

LVGL version (if used)

• 9.4.0

Additional context

Before I added the first style it was all OK because I could remove the line //${eez-studio LVGL_STYLES_DEF} from the styles.c template or even turn off "Styles", but now it's not a solution.
