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`.

This should generate libcrypto and libssl in the root of the OpenSSL directory. Rename the openssl-1.0.1j folder to openssl so CMake can find it.

If you have been building other components it is possible that the OpenSSL compile will fail based on the values other cross-compilations (tbb, bullet) have set. Ensure that you are in a new terminal window to avoid compilation errors from previously set environment variables.

####Intel Threading Building Blocks
Download the (Intel Threading Building Blocks source)[https://www.threadingbuildingblocks.org/download] and extract the tarball inside your `ANDROID_LIB_DIR`. Rename the extracted folder to `tbb`.
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`.
