    Hi

    -introduce
    I have used OpenCV with Qt Creator 3.1, MacOS 10.9.5 and have set the path in the .pro file and worked for me. i have now a program wich calculates the Disparity map of a stereo camera and then calculates and outputs the point cloud in a .txt file wich i can open with Matlab or Meshlab so far so good.
    but now i should display an elevation grid map direct form the camera data. so i thought first display the point clouds not with a extra program, thought PCL is good for displaying the points and then converting it to the elevation grid map..
    i tried to install PCL but got a lots of errors and tried different installation methods so i removed my usr/local folder and reinstalled OpenCV and PCL with Homebrew. after installing a few packages manual it worked.
    So OpenCV works again if i use the .pro file. My target is to compile Ocv and PCL code in one program..

    now for first i would like to use PCL and tried this tutorial or an other minimal example?
    http://pointclouds.org/documentation/tutorials/qt_visualizer.php
    but im really new to this all and don't know much of it.
    can't get cmake working, does someone know how to

    or wich INCLUDEPATH and LIBS i have to add to the .pro file that it works? then i think it would work perfect also with OpenCV..

    same asked here http://www.pcl-users.org/Qt-and-PCL-and-OpenCV-td4036749.html
    with some cmake progress but i have no real clue what to do there

    and after that how can i use Ocv and PC,L is now only the cmake file used an i have also to add Ocv in cmake or is the pro file also used?
    for the elevation grid map its better to make a new i think when i got pcl working

    found this old thread but no solution in it only that it worked :-/

    thx very much
