I downloaded OpenCV and tried to compile an example code using my Cygwin gcc complier. But I couldn't find any prebuilt libraries (such as libopencv_highgui) for Cygwin under opencv/build/x86 directory. There is a Mingw directory which contains the libraries for Mingw GCC. But I have only Cygwin GCC installed. So where is the prebuilt library directory for Cygwin GCC? Thanks.
