35 # This package tries to find the TinyXML-2 library. It will consider
36 # the directory ${TinyXML2_DIR} in its search. Upon exit, the
37 # following variables may be set:
39 # TinyXML2_FOUND - TinyXML-2 was found
40 # TinyXML2_INCLUDE_DIR - TinyXML-2 include directory
41 # TinyXML2_LIBRARIES - TinyXML-2 libraries
42 # TinyXML2_LINKS_OK - TinyXML-2 libraries link correctly
43 # TinyXML2_VERSION - TinyXML-2 version string as "major.minor"
