Yes, if a dependency is absent it is simply left out. See
contrib/vhost-user-scsi for an example where the executable is disabled.
Instead, if you want a dependency to be mandatory you have two choices:
- to break the build you use "required: true", see the SDL conversion
for an example
- to disable executables there is a thing called disabler but we're not
using it because it's confusing. I was thinking of adding an
"or_disable()" method to dependency objects, but I have never
contributed it.
