Invalid value for SpecUtils_FLT_PARSE_METHOD: default_value (attempt to build on macOS Tahoe)

[dmwco]

Hi Will,
This occurs after git clone https://github.com/sandialabs/SpecUtils. cmake .. in a build subdirectory fails with this message.
Any idea how to fix this?-Thanks.

@dmwco I think you need to specify a float parse method:

cmake
   -DSpecUtils_FLT_PARSE_METHOD="FastFloat" \
   -DSpecUtils_FETCH_FAST_FLOAT=On \
    ../

Here's more info about that option:

Choose one of: FastFloat, FromChars, boost, strtod.
Boost is fastest, FromChars requires a C++17 conformant compiler and runtime (note Apple clang does not implement),
FastFloat requires having the header somewhere findable (or Fetching it), and strod is the slowest.

Many thanks. Sorry to have overlooked the 'Relevant CMake Build options". boost worked, and the following 'make' did as well. This is for a macports user on macOS 26.2
