Get other third-party dependencies: libraries with extra functionality like decoding videos or showing GUI elements libraries providing optimized implementations of selected algorithms tools used for documentation generation and other extras. Install CMake from the official site or some other source. XCode IDE is used to build software for OSX and iOS platforms. Native toolchains for Android are provided in the Android NDK. On Windows it can be Visual Studio IDE or MinGW-w64 compiler. On *NIX platforms it is usually GCC/G++ or Clang compiler and Make or Ninja build tool.

OpenCV uses CMake build management system for configuration and build, so this section mostly describes generalized process of building software with CMake. This section gives a high-level overview of the build process, check tutorial for specific platform for actual build instructions. It can happen that existing binary packages are not applicable for your use case, then you'll have to build custom version of OpenCV by yourself. System packages in popular Linux distributions ( ).Other organizations and people maintain their own binary distributions of OpenCV. Packages for Android, iOS and Windows built with default parameters and recent compilers are published for each release, they do not contain opencv_contrib modules. In many cases you can find prebuilt version of OpenCV that will meet your needs. There are two ways of installing OpenCV on your machine: download prebuilt version for your platform or compile from sources. Next Tutorial: OpenCV configuration options reference
