<xFFC> "We can have them as git submodul..." <- Fully agree. In fact, I wrote an alternative CMake that vendors Boost, BoringSSL (replacing OpenSSL), ibsodium, and unbound, with git submodules. This is only for building the wallet library for Android, but maybe it could be upstream with some changes. See Boost for example: github.com/mollyim/monero-wallet-sd…d/src/main/cpp/boost/CMakeLists.txt
