The use of a setup file in sketches only works in certain circumstances.

examples/Generic/Sketch_with_tft_setup/Read_Me.ino

-/*
-It is possible to bypass the blockage put in place by the Arduino IDE so that a setup file can be included
-by a sketch.
-
-The procedure is as follows:
-
-1. Find the folder containing the boards.txt file for the processor board package you are using. To do this
-   click the IDE menu "File->Preferences". At the bottom of that window click the link to the preferences.txt
-   file. This will open a folder. Navigate to find the folder containing the "boards.txt" file for the
-   processor you are using. Example paths for RP2040 and ESP32 are:
-
-   C:\Users\xxxxx\AppData\Local\Arduino15\packages\rp2040\hardware\rp2040\2.5.2
-   C:\Users\xxxxx\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.4
-
-2.  Copy the platform.local.txt file to that folder. A copy of the "platform.local.txt" is in this sketch
-    folder, press Ctrl+K to open the folder.
-
-3.  Close the Arduino IDE and open it again so the added file is recognised.
-
-4.  This step is already done in this sketch, but to adapt you own sketches, open the sketch and add a
-    new tab, "tft_setup.h" in the main sketch, put all the tft library setup information in that header.
-    The tab header name must be tft_setup.h
-
-  IMPORTANT:  You will need to remember to add the platform.local.txt file again if you upgrade the IDE or
-  the board package version. Note that the file must be added to each processor board package you are using.
