How are you folks getting QT3 and QT4 to coexist

I'm looking at the latest Slackware release. Looks like the QT4 location is defined
by the QT4DIR environment variable and not QTDIR. That is good news.
Another difference is in the KDE3 days, QTDIR pointed to /usr/lib/qt, which was a sym
link to /usr/lib/qt-3.3.8b. In the latest Slackware release, the QT4 files are installed
directly to /usr/lib/qt and there is no sym link.
If I understand correctly, when I build a QT3 package on a QT4 system, I should compile
QT3 to install at /usr/lib/qt3 and then set a QTDIR environment variable to that location
before compiling 3.5.10/Trinity packages.
Does this sound correct?

You can use -DQT_LIBRARY_DIRS and -DQT_INCLUDE_DIRS with cmake to specify this.
