The platform files are located in WICED-Smart-SDK/Platforms. You can select the platform by edit the make target. For example, target "hello_sensor-BCM920736TAG_Q32 download" means you select the platform BCM920736TAG_Q32.
If you are using the CYBLE-013025 EVAL board, you need to add the platform files refering the KBA here: Platform Files for CYBLE-013025-EVAL - KBA220379
Did you mean renaming (right click -> edit) the make target "find_me-BCM920737TAG_Q32" to "find_me-CYBLE_013025_EVAL"?
Yes, you can edit the original make target. Or copy and past to create a new one.
