Just a short note if anyone is looking for a build system with an out-of-the-box Kconfig support: https://build2.org/blog/build2-kconfig.xhtml As part of this effort we've also written a Kconfig language guide, finding the official documentation to be more of a reference: https://build2.org/libbuild2-kconfig/doc/build2-kconfig-manual.xhtml#lang
