opencv and qt handling can be dropped since switch to an active fork in
commit 456a739831 as they are only used
when examples are enabled resulting in the following warning:
CMake Warning:
Manually-specified variables were not used by the project:
BUILD_DOC
BUILD_DOCS
BUILD_EXAMPLE
BUILD_TEST
BUILD_TESTING
BUILD_TESTS
CMAKE_DISABLE_FIND_PACKAGE_OpenCV
CMAKE_DISABLE_FIND_PACKAGE_Qt5
While at it, also drop BUILD_EXAMPLES which is already passed by
pkg-cmake.mk
