[CMake] CMake 2.6.2 can't find QtCore

[Serhii Piddubchak]

Hello, I'm using OpenSUSE 11.0 and trying to build software that uses QT.
I have QT and QT-devel packages installed but CMake says it Can't find QtCore.
I've posted a question about this to a project's forum here:

http://www.hedgewars.org/forum/viewtopic.php?id=648

They said it could be a CMake bug.
Here is the log(versions of cmake and qt are included):
