Failiure to build DAGMC with Double Down

[makeclean]

Looks to be a recently introduced bug in the DAGMC_macros.cmake file, where looking to compare the version number of double down. The issue is however in the ddConfigVersion.cmake produced from the DD build, the version number is set as a string "1.1.0" for example, but the DAGMC_macros.cmake file compares against against I dont really know what - the number is input as 1.1.0 - but its not a string nor an int.

I think either double down should be setting DD_MAJOR_VERSION 1 & DD_MINOR_VERSION 1, and those get checked in the macros file, or something similar. I'm surprised CI passes right now as is. Happy to fix, but need to know how DD should be fixed before upstream changes are made.
