[CMake] Build multiple lib

[Andrea Galeazzi]

  Hi everybody,
I've got a static lib project in vc6 as follow
lib1
lib2
......
libN
MainLib

The MainLib doesn't actually have any source but it depends form all the 
other projects (lib1,.....,libN) so it builds a static lib which 
contains all the ones.
Now my problems is how to write a CMakeLists in order to reproduce both 
the same build and the same structure of solution in VS 2010 as the 
original one.
Does anybody have any ideas?
Cheers
