So for command line cmake, you set PATH or add a -D flag to cmake with
the qmake you want to use.
With cmake-gui, it becomes interactive, and you can just fix what you
don't like.
BTW, only Qt 3 recognizes QTDIR, unless you want to use it yourself for
convenience.

I'm having a problem with FindQt*. I have numerous versions of Qt4 installed:
usr/local/Trolltech/Qt-4.1.1
/usr/local/Trolltech/Qt-4.1.5
/usr/local/Trolltech/Qt-4.2.3
/usr/local/Trolltech/Qt-4.3.5
/usr/local/Trolltech/Qt-4.4.3
/usr/local/Trolltech/Qt-4.5.0-rc1
As well as the stock versions of Qt3 and Qt4 that came with my distro
in /usr/lib.
I've written a simple CMakeLists.txt for one of the Qt examples, based
on recommendations about a seemingly related problem in this thread:
http://www.cmake.org/pipermail/cmake/2009-March/027702.html
Here is the file:
=========================================================
cmake_minimum_required(VERSION 2.4)
set(CMAKE_VERBOSE_MAKEFILE "YES")
set(DESIRED_QT_VERSION 4)
set(QT_QT_LIBRARY "")
set(QT_QMAKE_EXECUTABLE /usr/local/Trolltech/Qt-4.3.5/bin/qmake)
find_package(Qt4)
include(${QT_USE_FILE})
message(${QT_LIBRARY_DIR}) # prints "/usr/lib"
message(${QT_INCLUDE_DIR}) # prints "/usr/lib/qt3/include"
qt_wrap_cpp(DUMMY_LIB_NAME MOC_FILES slidersgroup.h window.h)
add_executable(myexe main.cpp slidersgroup.cpp window.cpp ${MOC_FILES})
target_link_libraries(myexe ${QT_LIBRARIES})
=========================================================
The result of running "cmake CMakeLists.txt ; make" for CMake versions
2.6.4, 2.6.3, 2.6.2, 2.6.0, and 2.4.8 all produce the output in lines
(1) and (2). CMake 2.4.8 additionally reports "-- Found Qt-Version
4.3.5"(!).
I've renamed the qmake that comes installed on my system, and changed
PATH and QTDIR env variables in an effort to get CMake to find the
right version of Qt. Any idea how I can fix my CMakeLists.txt and/or
system to fix this problem?
Thanks in advance.
