A minor correction here: it should be endmacro(PRINT_VALUES).

This is because each item of the list stored in your variable plugin_STR gets
assigned to a different argument in your macro. This should fix it:

macro(PRINT_VALUES  list)
  FOREACH(arg ${ARGV})
    message("File: ${arg}")
  ENDFOREACH(arg ${ARGV})
endmacro(PRINT_VALUES)

You could do that by specifying the variable NAME instead of its VALUE:

macro(PRINT_VALUES  list)
  message (STATUS "Files to process in the macro PRINT_VALUES ${${list}}")
endmacro(PRINT_VALUES)

file(GLOB plugin_STR  *.c *.cpp *.cxx *.h *.hpp)
PRINT_VALUES(plugin_STR)
