[CMake] Executable in the main directory

[Enrique Izaguirre]

Thanks a lot Eric

Actually I am trying to move a project already done to CMake, and it doesn't
have any executable in the top directory, it is now done in Windows under
Visual Studio.

In the top directory I have a CMakeLists,txt that calls each one of the
subdirectories in which I have also their respective CMakeLIsts.txt.

But I don't know at the end how to put everything together in an executable.
Because each directory compiles independently, like a module. I don't know
how it is done in Visual Studio.

Thanks again

Enrique
