Hmm.  Isn't this bit something that we should actually backpatch?  It
feels wrong to not enforce lz4 to not_found_dep in this meson path.
So this looks unrelated to the switch of the default value.

I don't think this change is correct, or at least it's not required, and 
you won't find it in the handling of other dependencies.

The point of assigning not_found_dep is to make lz4.found() return 
false, but in that particular code location lz4.found() is already false.
