Don't set a default search path; use CMake's default

Browse Source 
If we set a default search path ourself, then this will be used if we
specify a SuiteSparse_ROOT with error! Instead, we should just leave
our SuiteSparse_SEARCH_PATH variable empty and then let CMake fill in
its defaults. If there is a directory specified on the other hand
(indicating that we want exactly that location), only use that and
turn all the default paths completely off.
