This is so great, thank you. The CMake fetch content currently points to your fork; would you like to keep it that way or use this one eventually

I don't think it does...

FetchContent_Declare(supplemental_test_files
  GIT_REPOSITORY https://github.com/fastfloat/supplemental_test_files.git
  GIT_TAG origin/main)

Where does this data come from? I was puzzled by this in fast_float

It comes from https://github.com/fastfloat/supplemental_test_files.git

The idea is that instead of dropping lots of heavy data files directly in your repo, you pull them out if you want to test exhaustively the code.
