    1 # FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME (DEFAULT_MSG|"Custom failure message") VAR1 ... )
    2 #    This macro is intended to be used in FindXXX.cmake modules files.
    3 #    It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
    4 #    it also sets the <UPPERCASED_NAME>_FOUND variable.
    5 #    The package is found if all variables listed are TRUE.
    6 #    Example:
    7 #
    8 #    FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)
    9 #
   10 #    LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and 
   11 #    LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE.
   12 #    If it is not found and REQUIRED was used, it fails with FATAL_ERROR, 
   13 #    independent whether QUIET was used or not.
   14 #    If it is found, the location is reported using the VAR1 argument, so 
   15 #    here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
   16 #    If the second argument is DEFAULT_MSG, the message in the failure case will 
   17 #    be "Could NOT find LibXml2", if you don't like this message you can specify
   18 #    your own custom failure message there.
