Description

Hello,
I am working with OF version 0.7.4 and Codeblocks v. 12.11.
I am getting the following 6 linking errors (undefined references):

Research direction

Start by inspecting addons/ofxOpenCv/libs/opencv/lib/win_cb and the Code::Blocks linker configuration for the missing OpenCV symbols. Reproduce the OF 0.7.4 build and identify the relevant library linkage; the issue is done when the listed undefined references no longer prevent linking.
