    FindLibXml2: Restore compatibility with projects setting LIBXML2_LIBRARIES · d1a77565
    Brad King authored
    In commit a1b38865 (FindLibXml2: Switch to standard module variable
    names, 2017-07-11) the cache variable used to store the find_library
    result was renamed.  This breaks projects that set the old variable name
    explicitly.  Fix compatibility with such projects by using the old
    variable as a default if it is set and the new one is not.
