Right now for shader crate to compile crate-type = ["dylib"] is needed to be specified in Cargo.toml.

This is annoying in case when a library is not just a shader, but also a regular dependency of other crates since this makes compiler generate extra libshader_crate.so shared objects in target/{release,debug}.

This can be worked around with cargo rustc --crate-type dylib when compiling normally, so maybe codegen backend or cargo-gpu could do something like that transparently and implicitly?

Feel free to move this into cargo-gpu repository if it makes more sense to be there. Has nothing to do with cargo-gpu.
