OpenCV 3.4.5

OpenCV 3.4.4

tested with NDK 17b (17.1.4828580)

OpenCV 3.4.3

OpenCV 3.4.2

OpenCV 3.4.1

Found via `codespell -q 3 --skip="./3rdparty" -I ../opencv-whitelist.txt`

- configuration files for ABIs configuration
- use builtin Android NDK's toolchain by default (force flag to use OpenCV's toolchain)
- default values for 'work_dir' and 'opencv_dir'

- fix Javadoc:
  - generate Javadoc after gather step to process all Java files (including Android 21)
  - generate into 'OpenCV-android-sdk' directly without additional copy step
- use smart copy/move utility functions ('shutil' doesn't well with existed destination)
- by default move files to reduce pressure on storage I/O (> 800Mb)

Avoids this error message with CMake 3.10:
CMake Error: CMake was unable to find a build program corresponding to "Ninja".
CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.

Related changes is that pkg-config tool is found (/usr/bin/pkg-config).

This makes it possible to compile OpenCV with for instance ndk-r16

OpenCV 3.4.0-rc

OpenCV 3.3.1

OpenCV 3.3.0

- eliminate CMake 3.5+ warnings
- removed usage of dropped "OPENCV_CAMERA_MODULES" variable
- partial support for Android NDK 11+

3.2.0-rc

The INSTALL_NAME_DIR property of a target specifies how a dynamic library should
be found on OS X.  If INSTALL_NAME_DIR is not specified the loader will search
relative to the standard search paths.  If specified it should either be
an absolute path or relative path prefixed with either @executable_path,
@load_path, or @rpath.  Specifying "lib" does not make sense here and
causes linking error as documented here:

This patch removes INSTALL_NAME_DIR everywhere it is set to "lib".
An alternate solution would be to set an absolute path like
"${CMAKE_INSTALL_PREFIX}/lib" or relative path like
"@executable_path/../lib".  However, if there is not specific need for
specifying a path, it is probably best left unset.

The Android NDK would be moving to Clang as its default compiler
in the future. This patch allows OpenCV to build with the default
c++_shared / c++_static

TEST=Builds OpenCV with -DANDROID_TOOLCHAIN_NAME=
aarch64-linux-android-clang3.6 -DANDROID_STL=c++_shared

- IPP is disabled by default when compiler is mingw (couldn't make it
work)
- fixed some warnings
- fixed some `__GNUC__` version checks (for correctness and convenience)
- removed UTF-8 BOM from hough.cpp (fixes #5253)
