If you have two shader crates, one has to wait for the other to finish compiling before it can compile. That's a good thing, as you don't have to recompile any dependencies twice.
But if you have two shader crates with differing capabilities or features, they are forced to do a clean rebuild every time, adding 30s each build, even if nothing changed. Explicitly specifying a target dir enables me to specify a separate build dir for each shader crate and work around this issue.
I do think a better policy wrt. capabilities and features will be needed in the future, but this will do for now.
