# The strategy for this Docker example is to download the C++ SDK release artifacts and use those instead of compiling
# from source. This is for example/CI purposes only; generally it's better to build from source to ensure all libraries
# are compatible.
#
# Since we require a newer version of boost than is available in Ubuntu 22.04, we grab it from a PPA (mhier/libboost-latest).
#
# The SDK dynamic libs expect the boost libs to follow a specific naming convention, which isn't what
# the libraries from the PPA follow ('-mt' suffix is added to indicate the libraries are built with multithreading support enabled.)
#
# It's not 100% clear if these libraries are multithread enabled (build logs in the PPA seem to indicate it),
# but even so, the C++ SDK is single-threaded.
#
# To workaround, add symlinks with the expected names.
