[CMake] Problem with a macro

[Leopold Palomo Avellaneda]

Hi,

I'm trying to develop a macro to create gmo files (binarys from .po) for a 
project that uses gettext. This macro gets some parameters,

The idea is that you have program: foo
a template with the strings: foo.pot (the potfile)
several languages to translate: ca en es de (the langs var)
and a place to put the translations: INSTALLDIR

to have a mo file, for each language to must:
msgmerge foo_LANG.po foo.pot
msgfmt foo_LANG.po -o foo_LANG.gmo

the last command generates the output.

The macro, creates a custom target: foo_pos 
with all the needed files.

This target is a dependency of another target (translations) because I can 
have several groups (domains) in my project, and with make translations I 
would like to create all.

My problem is that is doesn't work, doesn't do the job and I don't know what's 
is happening. 

Please, could some one look on it? I need that two different eyes look this.

Regards,

Leo
