config_file error when called with multiple arguments

[massich]

I'm using ac2cmake as suggested by @pfultz2 in this PR and I get this error:

CMake Warning (dev) at cmake/cget-recipe-utils-config.cmake:390 (configure_file):
  configure_file called with unknown argument(s):
   matio/src/Makefile
   matio/getopt/Makefile
   matio/tools/Makefile
   matio/test/Makefile
   matio/documentation/Makefile

If I understand properly the following snipped passes all the parameters I've used when calling ac_config_file here directly to cmake's configure_file. https://github.com/pfultz2/cget-recipes/blob/8a700affa6bd289db1c4044c34af1894df468920/cmake/cget-recipe-utils/cget-recipe-utils-config.cmake#L385-L390

which ends up violating configure_file's signature:

configure_file(<input> <output>
               [COPYONLY] [ESCAPE_QUOTES] [@ONLY]
               [NEWLINE_STYLE [UNIX|DOS|WIN32|LF|CRLF] ])

Any suggestions? Shall we do some sort of foreach(arg ${args}) and then call config_file with ${arg}, but if so how shall we construct the <input> or <output>?

Yea, it only takes one file, and you need to set the input and output file names.
