Very easy, just run cmake-gui in your build directory, and change CMAKE_BUILD_TYPE to "Debug". Then press Configure, then Generate and then run make - the result should be compiled as debug. Or when running from command line: opencv\build$ cmake -DCMAKE_BUILD_TYPE=Debug ../opencv What I found useful is setting CMAKE_BUILD_TYPE to "RelWithDebInfo" - it will be beuilt as release with all optimizations, but still have debug info embedded - very useful, because it is fast, and you still have the debug info when something crashes inside the OpenCV library.
