iOS and Android C++ Builds?

Could someone point me in the right direction to build the C++ for either iOS or Android architecture? Apparently there is a bug preventing the ios (https://github.com/mavlink/MAVSDK/issues/904) and attempting to follow the instructions ( “android make install”) as per documentation returns “this project no longer uses a Makefile, but relies solely on CMake.
Instructions on how to build for Android will come soon”

Do I need to study up on CMAKE? I’m guessing there is a challenge and that is why there aren’t android binaries pre-made like the other distributions?
