CMake build script

[ssrlive]

Add CMake build supporting in Android for tun2socks component.

Now we can create a CMakeLists.txt file to use it.

cmake_minimum_required(VERSION 3.4)
project("myapplication")
add_subdirectory(libancillary)
add_subdirectory(badvpn)

Once the script running finished, we get the file libtun2socks.so.

Thanks for the contribution. However, I recommend submitting this patch to upstream (@ambrop72's repo).

[ssrlive]

Since the Android version depends on libancillary, I don't think @ambrop72 will accept this patch.

Good point. Maybe first submit a PR to base without libancillary?
