Make autocoded files more visible

[timcanham]

With cmake using build caches and the F Prime cmake system generating the autocoded base classes, a frequent question is: How do I find the generated files?

Possible ideas:

1. Create symlinks in the source directory to the build cache directory.
2. The files aren't really target-specific. Can the generated files go in a different, predictable path in the build cache?

fprime-util info was designed to provide this and other information

fprime-util info
[INFO] fprime build information:
    Available directory targets: 'build'

    Available global targets: 'build --all' 'build --all --ut' 'check --all' 'check --leak --all' 'check --coverage --all'
  ----------------------------------------------------------
    Release build cache module directory: /Users/mstarch/code/fprime-infra/fprime-sw/Ref/build-fprime-automatic-native/Ref
    Release build cache: /Users/mstarch/code/fprime-infra/fprime-sw/Ref/build-fprime-automatic-native

The first line after ---------... is the path to the module's cache directory. Also note, there isn't "target specific" information here. Is this information insufficient?

[timcanham]

Isn't the build-fprime-automatic-*native* the target-specific part?

My proposal for 1. was to put a symlink in each directory that has fpp files to the build cache directory with the autocoded files for that fpp file.
