I am not sure if I fully understand how the build works but I assume that you
dynamically link to the mmc35240 library, is that correct? If so, then what
happens when, during runtime, the mmc35240 library is not on the library path? 
Will UPM still work or will it crash immediately (or not start up at all)?
If the former is the case then it looks like mmc35240 is a works-with
dependency and since you already re-distribute the header files in UPM you will
only need a works-with CQ for mmc35240. However, if the latter is the case then
it is a pre-req dependency and you will need to add the full source code of the
mcc35240 library to this CQ (not just the headers).
Or is there no full source code, i.e. the headers already also contain the
implementation?
