Built OpenCV highgui without GSTREAMER support but with PvAPI support fails, adapting cmake doesn't work
So basically I want to built OpenCV with only PvAPI support to be sure that it can connect to my AVT Manta camera instead of running through a own created script.
I put explicitly in cmake-gui and in command line all other video supports off, but still GSTREAMER stays on YES.
Video I/O:
DC1394 1.x: NO
DC1394 2.x: NO
FFMPEG: NO
codec: NO
format: NO
util: NO
swscale: NO
gentoo-style: NO
GStreamer:
base: YES (ver 0.10.36)
video: YES (ver 0.10.36)
app: YES (ver 0.10.36)
riff: YES (ver 0.10.36)
pbutils: YES (ver 0.10.36)
OpenNI: NO
OpenNI PrimeSensor Modules: NO
PvAPI: YES
GigEVisionSDK: NO
UniCap: NO
UniCap ucil: NO
V4L/V4L2: NO/NO
XIMEA: NO
Xine: NO
Result is that it first tries to connect to a camera index 0 using the GSTREAMER interface instead of through the PvAPI interface. Can anyone check if they have the same problem with the following extra build parameter
-D WITH_GSTREAMER=OFF

If you look into the CMake configuration there are only two possible solutions, either GSTREAMER 1 OR GSTREAMER 0.1. However there is not a single case where you can decide NOT to use GSTREAMER.
So now I am wondering if there is a reason for that?
EXTRA
Got it to worl but now it cant find the cam, non-opencv interface does however... I think it could be due to the camera not being connected to eth0 interface but eth1. The opening of the capture is not working.
CvCaptureCAM_PvAPI* capture = new CvCaptureCAM_PvAPI;
if ( capture->open( index ))
return capture;
