- Substituted HAVE_WINRT with WINRT - Fixed compilation issues in ocl.cpp and parallel.cpp - Fixed compiler issue for WP8: "C2678: binary '+' : no operator found which takes a left-hand - Fixed gitignore - Added #ifdef HAVE_OPENCL to remove compiler warnings in ocl.cpp - Used NO_GETENV similar to '3rdparty\libjpeg\jmemmgr.c; - Added ole32.lib for core module (for WindowsStore 8.0 builds) - Made OpenCV_ARCH aware of ARM Signed-off-by: Maxim Kostin <v-maxkos@microsoft.com>
