First of all, thank you very much for supporting the FASTBuild generator. I would like to use cmake and FASTBuild to build our own project, but I have found that the i18nNum code in the FASTBuild generator is currently written dead. There may be issues with the VS support for non English versions. Additionally, when generating BFF files, the PlatformToolset parameter was not set in the VCXProject type target to specify the current version of the toolset being used. I am not sure if there are any plans to optimize this in future versions.
