You can likely just compile the cpp_casting.cpp file with your normal switches; however, we recommend using all warnings and pedantic options available to you and suppressing nothing. The accompanying CMakeList.txt and related cmake/*.cmake will do this rather simply.
Tools required:
To use cmake, you will of course need have cmake available. We assume version 3.21 or better. Go to https://cmake.org for more information.
Linux/macos commands to do the work:
# Configure and generate
cmake -S . -B build/debug -DCMAKE_BUILD_TYPE=Debug
# Compile and link
cmake --build build/debug --config Debug
# You should see at least two warnings
# Execute the test
ctest --test-dir build/debug -C Debug -VVEnjoy!
