I have this in the toplevel Makefile:

  include $(TOP)/configure/CONFIG
  ifneq ($(words $(CALC) $(SYNAPPS)), 0)
    # with synApps calc module (contains scalcout)
    DIRS += srcSynApps
    srcSynApps_DEPEND_DIRS  = src
    streamApp_DEPEND_DIRS  += srcSynApps
  endif

So if you have defined either CALC or SYNAPPS in your RELEASE file, then 
StreamDevice assumes that this points to the place where to find 
sCalcoutRecord.h. Otherwise, the whole srcSynApps tree will be skipped.

Is is possible that you have installed but not yet build SynApps (or its 
calc module)?
