package/opencv4: new package opencv4 is not fully backward compatible with opencv3 as "a lot of C API from OpenCV 1.x has been removed.": https://opencv.org/opencv-4-0. Moreover, it should be noted that layout of include files as well as pkg-config filename changed since https://github.com/opencv/opencv/commit/a95673287433fc810eda2d88b94bb234298c4cd5 All these changes mean that most of buildroot packages (e.g. vlc, ffmpeg) are not compatible with opencv4. Here is the most important changes between opencv3 and opencv 4.5.1: - License is Apache-2.0 (https://opencv.org/opencv-4-5-0) - openjpeg is an optional dependency (enabled by default) since https://github.com/opencv/opencv/commit/0384eb7d8c1a31831704e31b8bdbfbc6ff854281 jpeg2000 can be enabled through openjpeg or jasper - pkg-config must be enabled with OPENCV_GENERATE_PKGCONFIG since https://github.com/opencv/opencv/commit/e755a2a6e48ae02dd5136a628cc4148566a08225 - cmake is not installed in /usr/share anymore so hook can be dropped - C++11 is required since https://github.com/opencv/opencv/commit/d4688e6474dcd59c1d66736b744a8049f386a90b Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> [Arnout: remove a few redundant dependencies from Config.in] Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> 2020-12-26 11:42:59 +01:00			`# Locally calculated`
