Does the CPPPATH work?

env.AppendUnique(CPPPATH=['/usr/include'])

If not try to append it before or after the EnableQtModules call. It should 
not, but it could be a difference.

core, processing and audioio, scons has two different options 'prefix' and 
'prefix_for_packaging'. Just use them. Sadly we don't have such option in the 
rest of the sconstructs (plugins, apps...) Maybe is something that we should 
eventually introduce.

The problem is about defining DATA_EXAMPLES_PATH macro as we do in line 131 
of the SConstruct. As the comment says, if you define the prefix as the 
(missing) prefix_for_packaging, the path in networks is set to that path. And 
won't work when installed. So, yes, definitelly we should add such scons flag. 
The fast workaround, modifying such a line to hardcode /usr.
