From 6ffe96d1e3f0289c2070e050cf8e1a30288e6d91 Mon Sep 17 00:00:00 2001 From: Alexey Gavrilov Date: Fri, 27 Mar 2026 14:03:55 +0700 Subject: Cmake build generator support: build stage Multi-target architecture implementation: each root source code directory presents the one *INTERFACE* target to it's subdirectory subtargets that link only as *STATIC* library. For instance, *arch* directory presents *Architecture* target then *Architecture* target has *CPUID*, *IO*, *PORT* and etc. dependencies Exact order of linking targets is: boot.o CRTIBUNDLE CRTNBUNDLE. Sequence destruction cause to UB. Please to pay attention to this.
