If the library is not part of your project, use FIND_LIBRARY to find it
and TARGET_LINK_LIBRARIES to link it to one of your targets.  If the
library is part of your project, just use TARGET_LINK_LIBRARIES.

If you want your headers to show up in a VS project, add them with the
source files as you suggested.  If you want to specify include directories
in which to find headers, use the INCLUDE_DIRECTORIES command.

This is correct.  Just specify the following order in the top-level
listfile:

SUBDIRS(lib_1 lib_2 lib_3 exec)

Don't forget to use TARGET_LINK_LIBRARIES in each library directory to
link it to those on which it depends.
