Build external libs

[amiuhle]

I'm trying to get stagenet running, so I tried compiling the external libraries myself.

I added android-openssl and monero as submodules and adjusted the build instructions accordingly. However when trying to build monero, I get an error saying "Boost older than 1.62 is too old to link with OpenSSL 1.1 or newer.".

I think I did all the previous steps correctly, it finds the previously compiled OpenSSL library, but then somehow says it's using the include dir at /usr/include. Also the version at opt/android/build/openssl is 1.1.0g, but it should be 1.0.2l I suppose?

-- Found OpenSSL: /opt/android/build/openssl/arm/lib/libcrypto.so (found version "1.1.0g") 
-- Using OpenSSL include dir at /usr/include

Any tips what I'm doing wrong?

PR #272 contains all the steps to build the android packages on a clean environment. assume that your PATH is corrupted by a previous installation of the ndk-toolchain or not all configure-options are set, or the ndk-toolchain is not in the PATH.
you can run the build-artifacts.sh in your development system when you remove the failsafe test in the beginning, but i strongly suggest docker or a separate VM to build.

changing files as user in /opt is not a good idea
PR #271 contains the changes that came up when I tried to follow the build-description in a clean VM

in my opinion submodules (as monero does) are a bad, as they usually cause issues (eg monero-project/monero#3825) and in your description for example no mention of the requirement of --recursive is made, leaving the user hanging with "where is build_all_arch.sh"

i think this is void with the new docker build system

Agreed, void.
