You need to click on Configure in order to select the compiler of your choice and then click on Configure again. In the latter case, all you need to do is specify the folder containing the OpenCV library source and the one that will contain the binaries. You can then run it using the command line, but it is easier to use CMake with its GUI ( cmake-gui).

Therefore, you need to download and install CMake.

It generates the required makefiles or workspaces needed for compiling a software library in your environment. CMake is another open source software tool designed to control the compilation process of a software system using platform-independent configuration files. To complete the installation process and build the OpenCV binaries, you need to use the CMake tool, available at. Therefore, you can skip the compilation step described in this recipe, unless you want a customized build with specific options. In that case, you are ready to start using OpenCV. Within these subdirectories, you should find directories such as vc10, vc11, and vc12 these contain the binaries for the different versions of MS Visual Studio. Check for the build directory it should contain the 圆4 and x86 subdirectories (corresponding to the 64-bit and 32-bit versions). Note that if you are working under Windows with Visual Studio, the executable installation package will, most probably, not only install the library sources, but also install all of the precompiled binaries needed to build your applications. Which operating system should you use? Windows or Linux? Which compiler should you use? Microsoft VS2013 or MinGW? 32-bit or 64-bit? The Integrated Development Environment ( IDE) that you will use in your project development will also guide you to make these choices.
This is indeed the point where you have to make a decision on the target platform that you will use to create your OpenCV applications. (Yes, it is open source!) However, in order to complete the installation of the library and have it ready for use, you need to undertake an additional step: generating the binary files of the library for the environment of your choice. Notably, you will find the sources directory here, which contains all the source files.
Once this is done, you will find a collection of files and directories that constitute the library at the chosen location. You will then need to uncompress it, normally under a directory with a name that corresponds to the library version (for example, in Windows, you can save the uncompressed directory under C:\OpenCV2.4.9). From there, you will be able to download the OpenCV package. From the OpenCV website, go to the DOWNLOADS page that corresponds to the platform of your choice (Unix/Windows or Android).
