Fix build between SMF and PCF by only building used SMF models
Changes
@tien-thinh.nguyen I do the FILE(GLOB...
stuff in build/used_models.cmake
. We should do the same for all the other common models (e.g. NRF, UDM, UDR).
Otherwise, we build all the models, which may not be needed, e.g. in this case PCF had to build all SMF models instead of 3 models it needed (the build also failed).
