+### Additional tools
+
+The project includes an [tools.cmake](cmake/tools.cmake) file that can be used to import additional tools on-demand through CMake configuration arguments.
+The following are currently supported.

+- `-DUSE_SANITIZER=<Address | Memory | MemoryWithOrigins | Undefined | Thread | Leak | 'Address;Undefined'>`
+- `-DUSE_CCACHE=<YES | NO>`
