Compile only shaders

[kirnuarp]

it would be nice if there would be an option to only compile the shaders so for example you wouldn't have to reopen the XCode project every time you change shaders and build the whole project.

Changes required would be something like this:

I agree. Would you like to create a pull request?

[kirnuarp]

created pull request. It's only quick fix and could probably be done better but it works for me
