[Qt-interest] How to relocate an custom build and install of Qt?

[Dave Peterson]

Hello,

I'm trying to build an installer on Windows and OS X for an app that is 
based on Qt, and currently includes alot of the Qt distribution itself 
such as demos, examples, plugins, etc.   As part of that effort, I need 
my libs and plugins to be relocatable -- i.e. work from where ever the 
user told my app to install.  I can't seem to get various parts of Qt to 
work in these random install locations, in particular I get missing 
plugins and occasionally DLLs too.  I also can't get PyQt to build 
against these relocated installs.  I believe these problems are related 
to the "builtin" properties shown by qmake when one does a 'qmake -query'.

Does anyone know where these values are stored and how I can change 
them?  I've scanned the qmake executable itself for the strings it 
outputs when doing 'qmake -query' but they clearly aren't in the file 
itself.  I've tried doing a 'qmake -set QT_INSTALL_PREFIX' but that just 
adds a new property rather than modifying the builtin one.

If I'm heading down the wrong path, what's the right way to take an 
'install' of Qt and relocate it to another location without having to 
rebuild it specifically for that new location?  Again, I'm particularly 
interested in Windows and Mac OS X.

Thanks in advance!
