.cmake files need more touchups

Start in fixup.ts and compare its handling with fix-machos and fix-elf, using the folly-targets.cmake example in the issue as the reproduction. Trace how installed dependencies are located and represented in generated CMake files. Done means paths to packaged software use v{{version.major}} rather than locking to a full dependency version.

Our fixup.ts should do the same thing fix-machos/fix-elf do in terms of locating our software and shortening it to use v{{version.major}} to prevent hard-locking version dependencies. So far, this has only bitten us in facebook code.
