This happens if you mix the executable names. If your subproject is say 
prototype1 the following will return the above error:

ADD_EXECUTABLE( prototype1 prototype1.cpp )

TARGET_LINK_LIBRARIES( prototype3 libfoo )


You have to write

ADD_EXECUTABLE( prototype1 prototype1.cpp )

TARGET_LINK_LIBRARIES( prototype1 libfoo )
