I'd say: use pkg-config and the result it gives you.

That way, you can tweak which library it should find by changing 
PKG_CONFIG_PATH

Yeah, that's a problem because Qt installs QtCore and QtCore_debug 
pkg-config data files. Not much to do here, though...

So, hint: don't install Qt into /usr/lib. :-)

No, use pkg-config. Which means, of course, we have to create and install 
the .pc files...
