[CMake] how to write a cmake function with 2 or 3 arguments?

[David Cole]

The mandatory function arguments are the ones that you name. Optional
ones go after the named args and are referenced via ARGV0, ARGV1,
ARGV2, ... or the ARGV and ARGN variables.

See function documentation for more info:
http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:function

Typically I use ARGN as a list of, for example, filenames:

function(do_stuff arg1 arg2)
  foreach(f ${ARGN})
    # do something interesting with file 'f'
    message("f='${f}' arg1='${arg1}' arg2='${arg2}'")
  endforeach()
  message("f='${f}' arg1='${arg1}' arg2='${arg2}' ARGV2='${ARGV2}'")
endfunction()


HTH,
David
