[CMake] Also install dependent libraries

[Jean-Pierre Bergamin]

Dear CMake users

We have a project directory layout like the following (where server and 
client use libraires in the directory libs)
myproject/server
myproject/client
myproject/libs

When installing the project from the top level directory, everything is 
fine. But although dependent libs are built when calling "make install" 
i.e. in the server directory, they don't get installed. Is there a way 
to also install these dependent libs?


Regards

James
