Recompiling poppler to support qt3

I'm trying to recompile poppler 0.16.2 to support qt3. I have qt3 compiled and installed. I receive the following error message during configure:

======================================== checking for libqt3... no configure: error: in `/tmp/poppler-0.16.2': configure: error: Qt development libraries not found See `config.log' for more details make: *** No targets specified and no makefile found. Stop. ========================================

I think the problem is configure can't find qt3. I have qt3 installed in /opt/trinity/lib/qt-3.3.8b.

Likely I have installed qt3 incorrectly.

I appreciate help where I might have gone wrong.

Thanks.
