+##### Build and Run Tests
 
-The CMake preset system suffers from combinitorial explosion. There is a makefile in the root of the repository to aid in running more configurations.

-The makefile will use your system compiler, `c++`, if no toolchain name is provided, otherwise it will use the toolchain in the etc/ directory to perform the build. The Ninja multi config generator is used, with configurations for `RelWithDebugInfo`, `Debug`, `Tsan`, and `Asan` configured by default.
+##### Build Production, but Skip Tests
+
+By default, we build and run tests. You can provide `-DBUILD_TESTING=OFF` and completely disable building tests:
+
+```shell
+# Configure build: build production code, skip tests (BUILD_TESTING=OFF).
+$ cmake -G "Ninja Multi-Config" -DCMAKE_CONFIGURATION_TYPES="RelWithDebInfo;Asan" -DCMAKE_TOOLCHAIN_FILE=etc/clang-19-toolchain.cmake -DBUILD_TESTING=OFF -B .build -S .

+# Build.
+$ cmake --build .build --config Asan --target all -- -k 0
