Compiling NuttX RTOS—what package contains Kconfig?

I would like to use the NuttX RTOS for an embedded programming project, but I need some standalone Kconfig tools like Menuconfig and kconfig-tweak. Ubuntu has these packaged as kconfig-frontends, but I can’t find the equivalent in openSUSE Tumbleweed. Is there a package I could install? Thanks!

You will get more help if you start with explaining what you are trying to do instead of how.

NuttX uses Kconfig as its build system. I needed to have kconfig-nconf installed so I could run make menuconfig. But it doesn’t matter, I just ended up building kconfig-frontends from source and installing in /usr/local.
