/// This build script is needed to run the examples on Linux.
/// Feel free to copy this to your own Bevy project.
///
/// Be aware that on Linux you also need to set LD_LIBRARY_PATH to include the libraries.
/// There are a few ways to do it:
///
/// If you are working with an IDE it's easiest to add this to the run configuration.
/// For example, in Rust Rover you set `Environment variables` to `LD_LIBRARY_PATH=./fmod/api/core/lib/x86_64:./fmod/api/studio/lib/x86_64`.
///
/// If you are running your executable directly (no IDE, no cargo) see https://www.hpc.dtu.dk/?page_id=1180
