lib (release) or libd (debug), can Qt resolv this for me?

In the Plug & Paint Example the .pro presents the following:

LIBS           = -Lplugins -lpnp_basictools

if(!debug_and_release|build_pass):CONFIG(debug, debug|release) {
   mac:LIBS = $$member(LIBS, 0) $$member(LIBS, 1)_debug
   win32:LIBS = $$member(LIBS, 0) $$member(LIBS, 1)d
}

Which, for that particular case, appends a d to the lib name in debug mode, pnp_basictools becomes pnp_basictoolsd. But it doesn't scale well, i.e.:

LIBS           = -Lplugins -lplugin_1 -lplugin_2 -lplugin_3

if(!debug_and_release|build_pass):CONFIG(debug, debug|release)
   win32:LIBS = $$member(LIBS, 0) $$member(LIBS, 1)d

Seems not to append d to plugin_2 and plugin_3.

So, may I ask for another method to add the d to the lib name in debug mode?

The issue was also mentioned here.
