The headers are used as

#include "hstore.h"
#include "ltree.h"
etc.

in the existing source code.

If you want to install the for use by others, you can do one of three
things:

1) Install them into $(pg_config --includedir-server), so other users
will just include them in the same way as shown above.

2) Install them in a different directory, but keep the same #include
lines.  That would require PGXS changes, perhaps a new pg_config option,
or something that produces the right -I option to find them.

3) Install them in a different directory and require a different
#include line.  But then you have to change the existing uses as well,
which would probably require moving files around.

Both 2 and 3 require a lot of work, possibly compatibility breaks, for
no obvious reason.
