I am trying to create a project using OpenCV with QT for the user interface but I am having some problems.

I am using QT creator 2.0.0 on Ubuntu 10.4 64 bit with OpenCV 2.1.0.

I have each component installed and working independantly, but I can't seem to get them to play nice together.

For instance: using CMake and the following CMakeLists.txt file:

Qt Code: 
  1. PROJECT( facedetect_proj )
  2. FIND_PACKAGE( OpenCV REQUIRED )
  3. ADD_EXECUTABLE( facedetect facedetect.cpp )
  4. TARGET_LINK_LIBRARIES( facedetect ${OpenCV_LIBS} )
To copy to clipboard, switch view to plain text mode 

Creator creates a project that compiles and runs just fine, but does not create a .pro file.

When I create just a QT project, it compiles just fine and seems to find the OpenCV libraries just fine in the IDE but then does not build properly. I get "undefined reference" errors for every function call using OpenCV. I am pretty sure that I need to include more in the .pro file for this to work but I am not sure how to do it or what to include. Please help me! Thanks!
