+The steps on Windows and Ubuntu are similar. There is the only one difference: makefiles are built with mingw32-make
+on Windows and native GNU make on Ubuntu.

+Required tools (download and install if it is required):
+  - CMake v3.0+ http://www.cmake.org/cmake/resources/software.html
+  - Cross-compilation toolchain for CMake https://github.com/taka-no-me/android-cmake
+  - Android NDK rev.10+ https://developer.android.com/tools/sdk/ndk/index.html
