Hello,<br><br>I'm having some trouble to use a cmake script correctly and i don't know why.<br>The cmake script come from the openCV library (you can find it here: <a href="http://opencv.willowgarage.com/wiki/Getting_started?action=AttachFile&do=get&target=FindOpenCV.cmake">http://opencv.willowgarage.com/wiki/Getting_started?action=AttachFile&do=get&target=FindOpenCV.cmake</a>) and it search for include and library files.<br>
<br>In this script you can setup the path where you want to look for these files, (or let the script search the default path).<br>The problem is that if i have to version of openCV (one in the default path and one in a special path), it alway select me the default path.<br>
<br>Here you have the important part of the script: <br><br>----------------------------------------------------- <br><br>MESSAGE(STATUS "OpenCV_POSSIBLE_ROOT_DIRS=${OpenCV_POSSIBLE_ROOT_DIRS}")
<br> <br>FIND_PATH(OpenCV_ROOT_DIR
<br> NAMES
<br> cv/include/cv.h # windows
<br> include/opencv/cv.h # linux /opt/net
<br> include/cv/cv.h
<br> include/cv.h
<br> PATHS ${OpenCV_POSSIBLE_ROOT_DIRS})<br> <br>MESSAGE(STATUS "Selected OpenCV_ROOT_DIR=${OpenCV_ROOT_DIR}")
<br><br>SET(OpenCV_INCDIR_SUFFIXES
<br> include
<br> include/cv
<br> include/opencv
<br> cv/include
<br> cxcore/include
<br> cvaux/include
<br> otherlibs/cvcam/include
<br> otherlibs/highgui
<br> otherlibs/highgui/include
<br> otherlibs/_graphics/include
<br> )
<br><br> <br>MESSAGE(STATUS "OpenCV_HIGHGUI_INCLUDE_DIR=${OpenCV_HIGHGUI_INCLUDE_DIR} ; root=${OpenCV_ROOT_DIR}")<br><br>FIND_PATH(OpenCV_HIGHGUI_INCLUDE_DIR
<br> NAMES highgui.h
<br> PATHS ${OpenCV_ROOT_DIR}
<br> PATH_SUFFIXES ${OpenCV_INCDIR_SUFFIXES} )<br><br> MESSAGE(STATUS "OpenCV_HIGHGUI_INCLUDE_DIR=${OpenCV_HIGHGUI_INCLUDE_DIR} ${OpenCV_ROOT_DIR}")<br><br>-----------------------------------------------------<br>
<br><br>And here you have the first execution of cmake script when the cache empty.<br><br>

<br></p>-----------------------------------------------------<br>
<br>Does anyone know why the result of OpenCV_HIGHGUI_INCLUDE_DIR=/usr/include/opencv and not /opt/opencv/1.1.0/include/opencv <br>even if both files /opt/opencv/1.1.0/include/opencv/highgui.h and/usr/include/opencv/highgui.h exist in my path.<br>
