You do not have to add CMAKE_LIBRARY_PATH and CMAKE_INCLUDE_PATH to those
FIND_* calls, that is done automatically.  And I checked the code, and
they are checked first.   How are you setting those variables?  (env or
cmake variables)   Also what are you setting them too.   I think there is something
wrong with those varibles and that is the cause of your problem.
