+#### `SDL_LIBC=OFF` and sanitizers
+
+Building with `-DSDL_LIBC=OFF` will make it impossible to use the sanitizer, such as the address sanitizer. 
+Configure your project with `-DSDL_LIBC=ON` to make use of sanitizers.

+Most often, you can avoid copying libraries by configuring your project with absolute CMAKE_LIBRARY_OUTPUT_DIRECTORY

+When using a multi-config generator (such as Visual Studio or Ninja Multi-Config), eventually add /$<CONFIG> to both paths.
