Message : Vulkan: Load layers relative to executable dir. Instead of baking in a relative path and expecting the app to run from a fixed directory, we can change the CWD at runtime so the layers can load relative to the current executable directory. Future alternatives could include modifying the layers SDK to provide a path dynamically, but for now the relative paths must be baked in at compile-time.
