The simplest way is to declare everything using a macro

  #define MAKE_NAME(n) mylib ## _ ## n

which the user of the code edits.  It can be made a bit more automatic
(so that it can be done without an edit) but it's dubious if it's worth
the effort because it only works in rather limited situations and is
needed in even fewer.

Yes, though I would not use the term "stringification" because suggests
using # which makes a string token from a macro argument.
