Sergiu Deitsch d71ec0cd1d cmake: support OPTIONAL_COMPONENTS in OpenCVConfig.cmake
find_package allows to specify optional components. This way, the
command will not fail if any of the components marked as optional was
not found. This is useful in cases where components such as xfeatures2d,
viz etc. are not available either because they were not compiled by the
user or package maintainers decided to not provide the packages at all.

The user can check the availability of the optional component using the
OpenCV_<component>_FOUND variable.

# ===================================================================================
# The OpenCV CMake configuration file
#
# ** File generated automatically, do not modify **
#
# Usage from an external project:
# In your CMakeLists.txt, add these lines:
#
# find_package(OpenCV REQUIRED)
# include_directories(${OpenCV_INCLUDE_DIRS}) # Not needed for CMake >= 2.8.11
# target_link_libraries(MY_TARGET_NAME ${OpenCV_LIBS})
#
# Or you can search for specific OpenCV modules:
#
# find_package(OpenCV REQUIRED core videoio)
#
# You can also mark OpenCV components as optional:
# find_package(OpenCV REQUIRED core OPTIONAL_COMPONENTS viz)
#
# If the module is found then OPENCV_<MODULE>_FOUND is set to TRUE.
#
# This file will define the following variables:
# - OpenCV_LIBS : The list of all imported targets for OpenCV modules.
# - OpenCV_INCLUDE_DIRS : The OpenCV include directories.
# - OpenCV_COMPUTE_CAPABILITIES : The version of compute capability.
# - OpenCV_ANDROID_NATIVE_API_LEVEL : Minimum required level of Android API.
# - OpenCV_VERSION : The version of this OpenCV build: "@OPENCV_VERSION_PLAIN@"
# - OpenCV_VERSION_MAJOR : Major version part of OpenCV_VERSION: "@OPENCV_VERSION_MAJOR@"
# - OpenCV_VERSION_MINOR : Minor version part of OpenCV_VERSION: "@OPENCV_VERSION_MINOR@"
# - OpenCV_VERSION_PATCH : Patch version part of OpenCV_VERSION: "@OPENCV_VERSION_PATCH@"
# - OpenCV_VERSION_STATUS : Development status of this build: "@OPENCV_VERSION_STATUS@"
#
# Advanced variables:
# - OpenCV_SHARED : Use OpenCV as shared library
# - OpenCV_INSTALL_PATH : OpenCV location
# - OpenCV_LIB_COMPONENTS : Present OpenCV modules list
# - OpenCV_USE_MANGLED_PATHS : Mangled OpenCV path flag
#
# Deprecated variables:
# - OpenCV_VERSION_TWEAK : Always "0"
