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

Hi,
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
I get the following errors when trying to build my Qt project:
CMake Error at C:/Program Files (x86)/CMake

Yes to both John, I did point the CMake gui to the position of the qmake.exe
within the bin, and it does come with whatever DLLs the source comes with.
I am using Qt 4.8.0 and the latest CMake gui for Windows (x86).
Some other things to get out of the way:
QTDIR is set to C:/Qt/4.8.0/bin, and
Roike! I finally got it to run with a bit of manual linker error fixing!
I`ve one more question though:
CMake Warning at CMakeLists.txt:51 (ADD_EXECUTABLE):

there is a cycle in the constraint graph:

Hello, thank you for looking at my CMake issues! I really appreciate it :)
I fixed the major issue you mentioned (Moving INCLUDE_DIRECTORIES above
ADD_EXECUTABLE), however this did not seem to fix anything. I still got the
errors I was receiving prior to that change, and I used absolute paths
The following is my CMakeLists file:
PROJECT(CppSampleQt01)
FIND_PACKAGE(Qt4 REQUIRED)
FIND_LIBRARY(SIMPLONLIB lv.simplon lib)
FIND_LIBRARY(SIMPLONIMGPROC lv.simplon.imgproc lib)
SET(CppSampleQt01_SOURCES include/lv.simplon.class.cpp camera.cpp main.cpp
mainwindow.cpp osdep.cpp paint.cpp)
The qt libraries are included in the target link flag (this project uses qt
of course), however the two lib files that exist in the lib folder in the
same directory are either not recognized. They draw up linker issues in the
compiler, even though I can tell through the cmake gui that it does find
Include it using the flags? Like so:
TARGET_LINK_LIBRARIES(CppSampleQt01 ${QT_LIBRARIES} SIMPLONLIB
SIMPLONIMGPROC) ?
Because when I did this, the libs were not found either.

Thank you John, this did work. I get the idea now, thank you.
I have another concern though, that I hope I can be helped with though it's
doesn't fall under the original problem.
