Changing the makefile template in build-system doesn't trigger a makefile regeneration #572
Description
Changing the makefile template in build-system doesn't trigger a makefile regeneration.
This is annoying because if we introduce new symbols in the simulator module, we can't trigger a build error if the symbol is missing because VCV Rack needs -undefined dynamic_lookup on macOS, and this will silently fail in Rack when loading the module, which makes it hard for the user to understand why it doesn't work anymore.
Must be because the action rule doesn't depend itself on the action source code?
