can't set compiler option in top level CMakeList

[dvescovi]

Not sure if this belongs in CubeMX or STM32 code for VS.

I have a CMAKE project generated from CubeMX.

When I build within VS Code IDE with the STM32 Extension I get several nocent warnings I would like to eliminate.

Some of these are deep in the HAL and/or the generated code produced by CubeMX.

ex:

warning: declaration of 'hrtc' shadows a global declaration

warning: cast increases required alignment of target type [-Wcast-align]

etc.

I tried several modifications to my top level CMakeLists.txt suggested by AI to suppress these warnings but NONE work.

I know this line:

include("cmake/gcc-arm-none-eabi.cmake")

brings in all the gcc compile options but I don't want to modify this file as it gets regenerated every time I do a CubeMX "GENERATE CODE"

 

Things I have tried are:

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wno-shadow")

target_compile_options(my_target PRIVATE -Wno-shadow)

set(MCU_GCC_FLAGS "${MCU_GCC_FLAGS} -Wno-shadow")

add_compile_options(${MCU_GCC_FLAGS})

add_compile_options(-Wno-shadow)

set(CMAKE_C_FLAGS_INIT "-Wno-shadow") include("cmake/gcc-arm-none-eabi.cmake")

add_compile_options("$<$<COMPILE_LANGUAGE:C>:-Wno-shadow>")

set_property(DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} APPEND PROPERTY COMPILE_OPTIONS -Wno-shadow)

 

NONE of these work.

 

HELP
