Just to be clear, `build-path' returns a path value, not a string....

...and passing a path to `dynamic-require' should work, although the
path must be absolute. (Use `path->complete-path' to explicitly convert
a relative path to an absolute path.)

When `dynamic-require' gets a path (as opposed to a string), it treats
it as a filesystem path, as opposed to a URL-like path.

To provide a string as a path to `dynamic-require', you can use a
quoted `file' form, usually constructed like this: `(file ,str).

I may misunderstand your goal, but my guess is that passing a path
value to `dynamic-require' is the best thing in this case.
