The preferred method is for the user to set CMAKE_INCLUDE_PATH and
CMAKE_LIBRARY_PATH appropriately, see
http://www.cmake.org/Wiki/CMake_Useful_Variables.  The advantage of this
approach is it greatly reduces the number of different variables that the
user has to worry about. Thus, it is actually a good thing that the user
doesn't have to worry about setting individual XXX_INCLUDE_DIRS and
XXX_LIBRARIES values for find modules that correspond to the standard.
