My experience is that you can cleanly distinguish between various Qt4
versions by simply putting qmake for the version you want first on
your PATH.
Do you seriously consider this a solution, or just a hack that works for
you? It breaks as soon as you have two packages
/path/a/foo
/path/a/bar
/path/b/foo
/path/b/bar
The user should not need to go to great contortions to use /path/a/foo
with /path/b/bar.
You obviously feel strongly about this, but your explanation of your
objections is not clear.
Have you ever tried setting the PATH? It is actually quite easy and does
not involve "great contortions".
All I do is execute
PATH='/home/software/qtsdk-2009.02/qt/bin:'$PATH
and from then on, cmake uses the version of Qt4 that I downloaded and
installed in the specified location. If I want the system version of Qt4
again (which I don't for my needs), I remove the above from my PATH.
It really cannot get much simpler than this.
