In case you have a plain structure of headers (no subdirectories), you can 
have this in each subproject:

  install headers : a.h b.h c.h : <location>whatever-you-like ;

In case you have header structure with directories, you can have this:

  install headers : includes/a/b/c.h : <location>whatever-you-like 
                                       <install-source-root>includes

  ;

and the header will be placed to "whatever-you-line/a/b/c.h".
