Thanks, that helped!

With that information, here is what I found:

...

For consistency, should the modules requiring 2.6 or 2.4.4 be
updated to 2.8?

IMO it's a good idea to update at least to 2.6. Lower versions definitely won't work...

I'm not sure about 2.8. It may be only a «soft» limit. On the other hand I don't suppose it will cause any problems... And nobody will test for compatibility with versions lower than 2.8... And nobody of users would be able to because tdelibs requres 2.8... so, go ahead =)

NOTE: I'm just successfully built tdebase and tdelibs with cmake versions 2.8.0 and 2.8.3.
