You need  INSTALL commands for everything you want to be in the package

For your example:

ADD_EXECUTABLE(DistanceBetweenPoints DistanceBetweenPoints.cxx)
INSTALL(TARGETS DistanceBetweenPoints DESTINATION bin) # Add this for CPack to work

Then both "make install" and "make package" will work , and there will be bin directory in the package  with DistanceBetweenPoints
executable in it.
