# Why are we doing this when Souffle-generated C++ clearly uses exceptions?
# Well, Google famously does not like C++ exceptions in its internal codebase,
# so we will need to explicitly override that in Raksha files everywhere we
# build Souffle C++ code to have Raksha build when imported into Google. This
# default acts as a simulation of that property of Google's internal codebase.

# Note: We usually try to keep the cxxopt and host_cxxopt consistent. That is
# not a good idea for this line. It appears that adding -Werror to host_cxxopt
# causes the compiler to use this flag when building dependencies that we build
# from source. This causes the build to fail if our source dependencies are not
# warning-clean. We also comment out -Wall so that we do not receive extra
# warnings from our third party packages.

# Annoyingly, in the fuzztest library, their attempt to turn off the `-Wpsabi`
