[CMake] CDash upgrade

[Mathias Bavay]

Hi!

I've just upgraded CDash from version 2.3.0 (git) to the latest git 
version (2.6 but reporting 2.5 on its front page). Everything worked, I 
see my projects and their configuration (icons, descriptions, etc) but 
no builds are shown... I've checked in the database itself, the table 
cdash/build is full of data (ie builds) but they don't shown up in 
cdash. What could be the reason?

Thanks!
Mathias
