I think I found the problem and it is related with how we use the CMake find_* commands (find_path, find_library, etc.) in DOLFIN. What we do now is to use the PATHS option for the FOO_DIR variables, however, according to the CMake documentation, we should really be using the HINTS option instead. The PATHS option is more like "search this path as a last resort" and should be used for hard-coded paths like /sw (fink), /opt/local (MacPorts), /opt, etc. I will replace PATHS with HINTS in the FindFOO modules in DOLFIN if there are no objections.
