Save CMake function parameter forwarding

Code

For anyone interested, this is the set_source_files_properties to set_property conversion function I came up with:

function(set_source_files_properties)
  set(FILES)
  set(I 0)
  set(PROPERTIES OFF)

  while(I LESS ARGC)
    if(NOT PROPERTIES)
      if("${ARGV${I}}" STREQUAL "PROPERTIES")
        set(PROPERTIES ON)
      else()
        list(APPEND FILES "${ARGV${I}}")
      endif()

      math(EXPR I "${I} + 1")
    else()
      set(ID_IDX ${I})
      math(EXPR PROP_IDX "${ID_IDX} + 1")

      set(ID   "${ARGV${ID_IDX}}")
      set(PROP "${ARGV${PROP_IDX}}")

      set_property(SOURCE ${FILES} PROPERTY "${ID}" "${PROP}")
      math(EXPR I "${I} + 2")
    endif()
  endwhile()
endfunction()
