[CMake] Finding (and linking) gettext with CMake 2.4.x

[Naram Qashat]

On the project I'm working on, one of the developers expressed interest in 
utilizing gettext to handle internationalization and localization.  I found that 
CMake 2.6.0 and newer have a FindGettext.cmake module which would allow us to 
utilize gettext for this.  However, I've made our CMake build files able to 
function under CMake 2.4.x as well, due to our users compiling our software on 
shells that may not have the latest CMake, and there is no FindGettext.cmake 
with those versions.  Is it possible to include FindGettext.cmake in the root 
directory of my project and utilize that if CMake 2.4.x is used?

Another related question has to do with linking to gettext.  I know that on 
Linux, gettext is built into gcc and doesn't need to be linked.  But I use 
FreeBSD as my main system to compile our project, and would have to link to 
libintl myself.  Would that just be a matter of searching for the intl library 
and adding it to the linker flags then?  And would this also apply to linking on 
Windows as well?

Thanks,
