[CMake] CMake does not find an header file, and ignores the classes found in several other header files.

[Toronto Andrew]

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):
  Cannot generate a safe linker search path for target CppSampleQt01 because
  there is a cycle in the constraint graph:

    dir 0 is [-DEIGEN_USE_NEW_STDVECTOR]
    dir 1 is [-DEIGEN_YES_I_KNOW_SPARSE_MODULE_IS_NOT_STABLE_YET]
    dir 2 is [-DBOOST_ALL_NO_LIB]
    dir 3 is [-DFLANN_STATIC]
    dir 4 is [ /arch:SSE2]
    dir 5 is [C:/Qt/lib]
      dir 13 must precede it due to link library [QtOpenGL4.lib]
    dir 6 is [C:/Program Files (x86)/PCL 1.6.0/3rdParty/Boost/lib]
    dir 7 is [C:/Program Files (x86)/PCL 1.6.0/lib]
    dir 8 is [C:/Program Files (x86)/OpenNI/Lib]
    dir 9 is [C:/Program Files (x86)/PCL 1.6.0/3rdParty/VTK/lib/vtk-5.8]
    dir 10 is [C:/Program Files (x86)/PCL 1.6.0/3rdParty/FLANN/lib]
    dir 11 is [C:/Program Files (x86)/PCL 1.6.0/3rdParty/Qhull/lib]
    dir 12 is [C:/SimplonSample2/lib]
    dir 13 is [C:/Qt/4.8.0/lib]
      dir 5 must precede it due to link library [QtGui4.lib]

  Some of these libraries may not be found correctly.

This stuff pops up when I try to include VTK and PCL as well, and I`m not
sure how to deal, any thoughts?

PS: I owe you a beer whenever you are in Toronto! I really appreciate all
the helpful info!
