Hello, Thank you for reporting this. In CMakePlatforms.cmake, can you comment out this line? message(FATAL_ERROR "Unknown platform ${CMAKE_SYSTEM_NAME}!")

There's nothing specific about RTM that should prevent it from running on FreeBSD to my knowledge but I don't have access to a box that runs it to validate.

Cheers, Nicholas

Commenting out that line did the trick. Thank you.

If you don't mind, I'll keep this ticket open for now to make sure I don't forget to make a fix for this in the next release. I'll make sure we handle more exotic platforms more gracefully, or at least ones I can't test locally with.

Thank you for reporting this! Cheers
