- removed OpenCV_LIB_DIR* vars (they are broken and not required anymore)
- OpenCVConfig.cmake doesn't contain ANDROID/CUDA code if there is no such support
- removed OpenCV2_INCLUDE_DIRS_CONFIGCMAKE, merged into OpenCV_INCLUDE_DIRS_CONFIGCMAKE
- fix hard-coded relative paths for OpenCV_INSTALL_PATH
- removed OpenCV_TBB_ARCH
- switch OpenCVConfig.cmake into 2-level mode for Android SDK

syntax of cmake "get_filename_component" changed after version 2.8.11

for cmake version < 2.8.11
  get_filename_component(<VAR> <FileName> PATH [CACHE])

for cmake version >= 2.8.11
  get_filename_component(<VAR> <FileName> DIRECTORY [CACHE])

Update OpenCVConfig.cmake

Update OpenCVConfig.cmake.in

Without the fix, OpenCV will compile and silently copy the compiled libs/executables to a location not prefixed with arch/vc14, and OpenCV won't be picked up by find_package and OpenCVConfig.cmake.

The check for BUILD_SHARED_LIBS had its logic backwards. If this
variable is not defined we must assume a build of static libs.

Make detection of x64 using the gcc's target triplet identical
to the one used in cmake/OpenCVDetectCXXCompiler.cmake.
Otherwise, MinGW-w64 setups will always be treated as x64 since
they contain "w64" as vendor key.

Fix typo that would always lead to detection of x86 for MinGW
builds in the OpenCVConfig.cmake file.

- 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

Allow to build samples via OpenCV binaries from distribution package
(find_package with OpenCV_DIR).
