[Qt-interest] Best way to deal with library dependancies with qmake

[Evan Teran]

So I have a project which depends on an external library. Is there a best 
practice for dealing with this? Is there any form of qmake time detection of 
dependencies available?

I suppose I could do something like this (my external dependency is boost):

 exists( /usr/include/boost/bind.hpp ) {
       message( "Required boost header not found, please check your 
installation" )
 }

The problem with this is that I would need to figure out where the header 
could be installed (not just /usr/include, since I plan to support windows 
as well).

option B is of course to make a "configure" script which do some probing and 
tweaks the .pro file (or could just generate a .pri file for inclusion, same 
difference really).

Is there something better or are these my options?
