SDL2 not found when attempt to run an example on macOS

[cjdell]

This is a nice library with lots of potential, however attempting to run the examples on macOS gives the following error, despite SDL2 being installed by brew:

  = note: ld: library 'SDL2' not found

For me, the workaround is to add an explicit reference to dependency sdl2 in the project's root Cargo.toml file:

[dependencies]
...
sdl2 = { version = "0.38.0", features = ["use-pkgconfig"] }

This allows the examples to build, i.e. with:

cargo run --example texture_mapping_demo --features std

Hope this is useful information to someone.
