That should be enough.
The initial error was like this:

- -- Performing Test HAVE_POPPLER_0_6
CMake Error: The following variables are used in this project, but they
are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the
CMake files:
Qt4__QTCORE
    linked by target "cmTryCompileExec" in directory
C:/kde/kde-mingw4/build/kde/kdegraphics-20080202/work/mingw4-Release-svnHEAD/CMakeFiles/CMakeTmp

CMake Error: Internal CMake error, TryCompile configure of cmake failed

( taken from
http://winkde.org/pub/kde/ports/win32/releases/nightly/20100109/logs/log-mingw4-kde_kdegraphics.txt
)

The error was reproducable on Windows & Linux & according to Christoph
it also works under Linux with this patch.

So please commit & backport in case the new FindQt4.cmake also made it
into 4.4 branch.

regards,
Patrick
