[cmake] get rid of `GLOB`s

Globbing considered harmful (in CMake, anyways). Usually what this does is add an extra step to the build process that can often take a very long time. This is really tedious to do though, but I'll leave this here as a reminder.

The issue names no files, tests, or entry points. Start by searching the repository's CMake configuration for GLOB usage and reviewing how those files enter the build. Done means replacing the relevant globs while preserving a working build, though the issue provides no detailed acceptance criteria.
