Modern builds and tooling
A build system, warnings and sanitizers catch mistakes before users do.
What you will be able to do
- Use target-based CMake: target_link_libraries and target_compile_options.
- Compile with -Wall -Wextra -Wpedantic in development.
- Run tests with sanitizers enabled.
In plain English
CMake describes targets and dependencies across platforms. Turn on warnings and treat them as errors. AddressSanitizer and UndefinedBehaviorSanitizer find bugs that tests miss; do not ship debug builds.
