-| Option | Effect |
-|--------|--------|
-| -D CMAKE_BUILD_TYPE=Debug | Debug info and no optimizations |
-| -D ENABLE_CCACHE:BOOL=ON | Speeds up recompilation |
-| -D CMAKE_EXPORT_COMPILE_COMMANDS=ON | Creates `compile_commands.json` for `clangd` language server |
-| -G Ninja | Use Ninja build system instead of make, which speeds up the build and doesn't require a `-j` flag |
