 Cross-compilation of OpenSSL has only been tested from an OS X machine running 10.10 compiling OpenSSL 1.0.1j. It is likely that the steps below will work for other OpenSSL versions than 1.0.1j.
 
+Download the (OpenSSL source)[https://www.openssl.org/source/] and extract the tarball inside your `ANDROID_LIB_DIR`. Rename the extracted folder to `openssl`.

 You will need the [setenv-android.sh script](http://wiki.openssl.org/index.php/File:Setenv-android.sh) from the OpenSSL wiki. 
 
 First, make sure `ANDROID_NDK_ROOT` is set in your env. `setenv-android.sh` needs `ANDROID_NDK_ROOT`.

+From the tbb directory, execute the following commands. This will set the compiler and archive tool to the correct ones from the NDK install and then build TBB using `ndk-build`.
