cmake tweaks

cmake tweaks

  • -w silences all warnings current and future.  We're not using this for development.
  • There's no real need to exclude files in Release mode.
    The linker may whine a little, but that's fine.
  • Quiet down message() calls that run every time.  They're fine if you can figure out
    how to run them only when doing the detection and cache them like all the others,
    but I don't like the noise seeing them every run.
  • cheaders is hard to read.  c_headers.
  • ../src/*mac* erroneously picks up SkLumaColorFilter on non-case-sensitive file systems.
    ../src/*_mac* seems fine.
