The snap contains binaries from .debs, we're not (re)building anything there.
The problem seems to be that Mir is looking in / to determine which graphics platform to load. If you have a "compatible" Mir between / and the snap, all's fine. But when you install a different version in /, the snap version is trying to find the system-installed one somehow.
