# By default OpenCV only requires the consumer's CUDA Toolkit to match the
# major.minor version it was built with. The CUDA runtime API is stable within
# a minor release and patch versions change frequently, so pinning the patch
# component forces needless rebuilds (issue #26965). Set
# OPENCV_STRONG_CUDA_VERSION_CHECK before find_package(OpenCV) to require an
# exact match including the patch component.
