Relocating Qt requires either patching the qmake binary or installing
a qt.conf file to help qmake find the libs in the new position. The
absolute include/lib dirs are hardcoded into qmake when its being
built. See http://doc.qt.nokia.com/4.7/qt-conf.html for the
file-format

Does that mean you didn't move Qt this time?

Did you start with a clean cache? The screenshot suggests you're
trying to mix debug and release Qt libraries, thats a very bad idea
anyways (QtOpenGLdd and QtGui4 are mentioned). So maybe things are
still not picked up as you think they are? The cache-file should have
more information.

And you should get rid of LINK_DIRECTORIES, thats not a good idea and
almost always the wrong fix to whatever linking problems you have.
CMake find-modules are supposed to setup the absolute path to
libraries in the variables they 'export', which can be used with
target_link_libraries directly. Same goes for the 'link_libraries'
call for MacOSX I'd say.
