CC-RX Compiler availability for Ubuntu


I'm trying to find a way to install the RX Compiler on my Ubuntu machine. I couldnt find any direct support for the RX family on the official download pages, nor any packages provides by docker or similar. Therefor I wanted to ask if there is any way to get access to the compiler alone without the need to install the IDE. 

Thank you for your help, it is very appreciated.

Best regards.
