I guess I'm facing a CMake's bug. I'm actually working with two Qt4
versions: Qt 4.4.2 (official distribution, including VS2008 integration)
and Qt 4.3.4 (open source distribution). I've set the QTDIR variable as
Michael suggested (in two places. Firstly in my own environment
variables and secondly in the system's variables) but it had not worked.
After that I downgraded CMake to 2.6.2 (official release), same problem.
Clinton, setting the QT_QMAKE_EXECUTABLE in CMake was the first thing I
tried (take a look at here
http://www.nacad.ufrj.br/~rnelias/paraview/qt.JPG). It should be the
easiest way. CMake keeps my set but mix with the other Qt stuffs with
the newest version (4.4.2). Thus, when I try to launch the compiled PV I
get an error message saying that it's not possible to find the entry
point of the procedure [EMAIL PROTECTED]@@[EMAIL PROTECTED] in
dynamic library QtGui4.dll. My guess, is that Visual Studio is "qmaking"
with version 4.3.4 and linking against 4.4.2.
By the way, should PV3 work with 4.4.2? Has anybody tried it?

If there's a qmake in your PATH, it takes precedence over whatever you
set QTDIR to be.
By the way, the use of QTDIR has been deprecated by Trolltech.
Another thing you can do is set QT_QMAKE_EXECUTABLE in the cmake-gui
before you hit configure for the first time, and it won't matter what
your PATH is.

Assuming you really meant Qt 4.3.4 and NOT Qt 3.3.4 here is what
you need to do.
Remove everything from your build directory so we can start clean.
Go to "My Computer" and add/check/set the QTDIR (Capitalization
counts) to your Qt 4 installation.
Launch CMakeSetup or CMake-GUI.exe and configure ParaView. You should
at most get a warning about the version of Qt your are using and the
"required" version.
Everything _should_ work.
Now, if you are really trying to use Qt 3 instead of Qt 4 then that
is not supported. YOu need at least Qt 4.3 to build ParaView.

Hi Michael,
there's something overriding my QTDIR because CMake still points to
the wrong Qt version. I've set both QT_QMAKE_EXECUTABLE and QTDIR to
3.3.4 version, but CMake still returns me a warning that I'm using
an unsupported version of Qt. Now I'm trying to understand all that
CMake sintaxe in FindQt4.cmake and UseQt4.cmake modules.
weird, isn't it?!

Hi folks,
I'm facing a curious problem here. I was using Qt-4.3.4 to compile
ParaView in a Windows machine and it had been working fine but
after installing a second version of Qt (4.4.2), CMake 2.6 (patch
2 RC-5) seems to be getting confused about which version it should
use. Even pointing QT_QMAKE_EXECUTABLE to Qt-4.3.4, CMake insists
in pointing all other stuffs to Qt-4.4.2 paths (QT_DOC_DIR,
QT_INCLUDE_DIR, QT_LIBRARY_DIR and so on...). In my environment I
have set QT_QMAKE_EXECUTABLE to Qt-4.3.4 but it's not solving the
problem. Is there any other environment variable that could be
used to force CMake in using the correct version of Qt?

Renato.

You can set QTDIR to the installation directory. CMake will try to
use that variable if it finds it. Also, once the Qt libraries and
stuff is set in a build directory it is pretty hard to get it to
change. Clearing the build directory and starting out again with
the QTDIR env variable set should help you find the correct version.
Alternately you can open the CMakeCache.txt and remove all traces
of ANY variable with QT in its name. This isn't exactly the
preferred way to trouble shoot this problem but has worked in the
past, plus saves all your compiled code from having to be recompiled.
