Well,

first of all thanks for all. After looking and testing a lot i have found a 
functional solution. See above:

Conceptually the main problem have been that I cannot have several custom 
target with the same name in the same directory. So, I was doing a bad 
implementation of your solution. The solution that I have found have been 
create a custom target for every file that I would like to copy and add them 
to the target as dependency.

So, by now it's working. 

Best regards,

Leo

endmacro (GETTEXT_UPDATE_LANG_PO dirOUTpo inputPo)
