I never encountered that problem... the only thing that would come to my 
mind is that maybe you have multiple installations on the system (like 
one from the package manager and one built from source) and thus files 
from another installation are used?
Or you could try to delete CMakeCache.txt from the build directory. If 
you then type make again you see where it found the gruel library.

Best,
