It is not true - when you modify project in TouchGFX designer and generate, it does generate new sources, however it does not update my CMakeLists.txt file. I solved this "problem" in my case, by manually adding TouchGFX sources to the project.

A new CMakeLists.txt file is added in the TouchGFX directory (it could be way smaller since I used some if statements to check if top level or not - for other reasons in my app):

cmake_minimum_required(VERSION 3.22)

# Debug message
message("Entering ${CMAKE_CURRENT_LIST_DIR}/CMakeLists.txt")

#
# Setup project if this is top-level
#
if (PROJECT_IS_TOP_LEVEL)

project(TouchGFX-simulator)
set(EXECUTABLE                      ${CMAKE_PROJECT_NAME})
enable_language(C CXX ASM)

endif()

#
# Setup all necessary include directories
#
set(touchgfx_include_DIRS
    ${CMAKE_CURRENT_LIST_DIR}/Middlewares/ST/touchgfx/framework/include
    ${CMAKE_CURRENT_LIST_DIR}/TouchGFX/generated/fonts/include
    ${CMAKE_CURRENT_LIST_DIR}/TouchGFX/generated/gui_generated/include
    ${CMAKE_CURRENT_LIST_DIR}/TouchGFX/generated/images/include
    ${CMAKE_CURRENT_LIST_DIR}/TouchGFX/generated/texts/include
    ${CMAKE_CURRENT_LIST_DIR}/TouchGFX/generated/videos/include
    ${CMAKE_CURRENT_LIST_DIR}/TouchGFX/gui/include
    ${CMAKE_CURRENT_LIST_DIR}/TouchGFX/App
    ${CMAKE_CURRENT_LIST_DIR}/TouchGFX/target/generated
    ${CMAKE_CURRENT_LIST_DIR}/TouchGFX/target
    ${CMAKE_CURRENT_LIST_DIR}/TouchGFX/simulator/
    )

#
# Scan for all necessary source files to be part of the build
#
file(GLOB_RECURSE graphics_core_generated_SRCS
            TouchGFX/App/*.cpp
            TouchGFX/App/*.c
            TouchGFX/generated/*.cpp
            TouchGFX/gui/*.cpp
            TouchGFX/gui/*.c
            TouchGFX/target/*.cpp
            TouchGFX/simulator/*.cpp
)

#
# Remove simulator files it this is not top-level project
#
if (NOT PROJECT_IS_TOP_LEVEL)
list(FILTER graphics_core_generated_SRCS EXCLUDE REGEX ".*/simulator/.*")
endif()
message("graphics source files: ${graphics_core_generated_SRCS}")

#
# Set executable when project is top-level
#
if (PROJECT_IS_TOP_LEVEL) 

# Add executable and 
add_executable(${EXECUTABLE})
target_sources(${EXECUTABLE}
    ${graphics_core_generated_SRCS})
target_include_directories(${EXECUTABLE} PRIVATE 
    ${touchgfx_include_DIRS})
target_compile_definitions(${EXECUTABLE} PRIVATE
    WIN32
    NDEBUG
    _CONSOLE
)

else()
# Register core library for the system
# This is not top-level library
add_library(touchgfx INTERFACE)
target_sources(touchgfx PUBLIC ${graphics_core_generated_SRCS})
target_include_directories(touchgfx INTERFACE ${touchgfx_include_DIRS})
endif()

# Debug message
message("Exiting ${CMAKE_CURRENT_LIST_DIR}/CMakeLists.txt")

And then top level CmakeLists includes it as subdirectory

# Add external libraries
add_subdirectory("../relative/path/to/new/cmakelists" touchgfx)
target_link_libraries(${PROJECT_NAME} touchgfx)

Each time I update TouchGFX project, I go back to top level CMake file and re-run build to add new files to build - using GLOB.

Isn't TouchGFX in charge to run these commands even before you come to CMake?

I wonder the same answer that MaJerle has asked. This website also might help: https://visualgdb.com/tutorials/arm/import/

No, I am certain TouchGFX does not run these commands.
Using an existing project, I opened TouchGFX designer (4.18), and modified some text "HELLO WORLD" > "HELLO SAILOR".
Then clicked "Generate Code". Below is the log:

Generate Code
    Generate
        Done
    Generate Assets
        make -f simulator/gcc/Makefile assets -j8
        Done
    Post Generate
        touchgfx update_project --project-file=simulator/msvs/Application.vcxproj
        Done
    Post Generate Target
        touchgfx update_project --project-file=../TestProj.ioc --platform=m4
        Done
    Done

It is running commands from the default makefile generated when the project was created. The only file changed is TouchGFX/assets/texts/texts.xml

Running CMake Clean Rebuild without the above solution still produces a build. Running this build does not change the text. The text shown is "HELLO WORLD".

If the above solution is added to the CMakeLists.txt and the project rebuilt, many more files in TouchGFX/generated are modified, and the build now shows the new text.

I'm sure a similar example can be demonstrated for Images.
