I added comments:

(propagated-inputs
      ; Headers contain #include <NetworkManager.h> and
      ;                            #include <libnm/NetworkManager.h>
      `(("network-manager" ,network-manager)))

(propagated-inputs
     ; Headers contain #include <ModemManager/ModemManager.h>
     `(("modem-manager", modem-manager)))

These comments should begin with ";;", not with ";".  Sorry, but I still
don't understand the reason.  What exactly does not work when these are
simple inputs?  Is it possible to avoid propagating?

Quoting the manual on the section on propagated-inputs:

So the fact that the headers of networkmanager-qt include headers from
network-manager, means that a library that uses networkmanager-qt also
needs network-manager's header files. After compilation if there
aren't any references to network-manager it won't be included in the
RUNPATH.

I think the equivalent for cmake packages is a find_dependency call
inside of /lib/cmake. In this case a library that links agains
networkmanager-qt doesn't need to link agains network-manager.

So to build hawaii-shell that depends on networkmanager-qt I either
have to add network-manager as an input or propagate it in
networkmanager-qt. I don't think that propagating the input hurts:

Ah, OK, I didn't know that, thanks for pointing!

I would write 'network-manager' instead of NETWORK-MANAGER.

Also there should be a reason for propagating (probably written as a
comment).  Ideally it should be avoided.
