I thought about that, but I couldn't find a way to generate a reasonable error message for the case that a user forgets to pass the required variable to their LLILC cmake invocation -- that would look the same from the perspective of LLILC's cmakefiles as the recursive invocation here which needs to quietly skip generating LLILC build files.
