[CMake] example of ctest --build-and-test

[Luigi Calori]

I have the following problem:
 a master cmake project that wants to configure and build a series of 
slave cmake projects
I' ve tried several hacking but not found an elegant solution.
I' ve read from the list that the

ctest --build-and-test


could be used for that but did not found any example: any suggestion?
The main reason for such a request is that I would like to have targets 
that download from CVS,configure and build projects, so to
use the master build phase as a kind of interface to all the tedious 
step of grabbibg things from the net, configuring and building.
Are there any examples ?

Thanks in advance
