Re: [CMake] CMake is unable to find QtCore!
Did you make the mistake of relocating your Qt installation? You could run qmake -query to see the paths it prints out, to make sure it matches your installation.

Haha spot on mate. I did so. To rectify, I reinstalled VTK and CMake, fixed the PATH var and the QTDIR.

I reinstalled the 4.8.2 binary, why is this not enough? Well, patching the qmake binary is exactly what happens when you use Nokia's binary installer for Qt and it patches qmake to the install location you chose during the installation. The patching/qt.conf file is only necessary if you then move Qt again to another location. FindQt4 now actually finds 4.8.2 as opposed to 4.8.0, however some flags like QT_USE_FILE and QT_QTGUI_LIBRARY seem to still point at 4.8.0 prompting some linker issues during the build.

You can actually find out how cmake gets qt libs etc. from qmake: qmake -query produces a list of paths. CMake will use these with find_library/find_file and prefers them over the standard lookup paths of those functions (by using them as HINTS). So if qmake produced QT_INSTALL_LIBS:C:\Qt\4.8.2 then CMake should find all Qt libraries in that location. Just for reference, the CMakeLists is found http://pastie.org/4466367 here if need be.

Not without seeing the cmake cache or some output what the various cmake variables you're using actually contain. There is nothing in the CMakeLists file that seems like it may be causing it. Could it be a way the other libraries are built (VTK ?) Could be, if the other cmake variables contain Qt debug libs, since you use them with link_directories and link_libraries they could influence the sample-target.
