### Block of including .json5 files. Files of this block must be included before the app.cmake

#[[ Set path of mbed_app.json (necessary at all times) ]]
set(MBED_APP_JSON_PATH mbed_app.json5)

###--------------------------------------------------------------------------------------------------- 
#[[ This part is dedicated for custom targets only! The settings below activate targets from
    custom_targets.json5 and upload method config. If custom targets are not used the lines below should be commented. ]]

#[[ Here set path for custom_targets.json5 (this is our default) ]]
#set(CUSTOM_TARGETS_JSON_PATH custom_targets/custom_targets.json5)

#[[ Here you can set path for custom upload config .cmake (optional example) ]]
#set(CUSTOM_UPLOAD_CFG_PATH ${CMAKE_SOURCE_DIR}/${MBED_TARGET}/${MBED_TARGET}.cmake)

#[[ Note: For custom target you need also an upload method and we have few options how you can do that
    - use the variable CUSTOM_UPLOAD_CFG_PATH above to set the location of your config file
    - use the default expected path for custom targets upload method config file:
      MY_PROJECT/custom_targets/upload_method_cfg
    - of course you can set upload method parameters directly via cmake in this file

# the bare metal version. This if statement checks to see which is in use and links it.
# Important: The mbed-os and mbed-baremetal libraries are object libraries, so they should ONLY be
# linked to executables, not to other libraries. Libraries should link to `mbed-core-flags` instead.

# upload method.

   your target, you can do that with mbed_set_post_build(${PROJECT_NAME} path/to/linker_script.ld) ]]
