# CMakeLists.txt -- Linux / native (host) build for the portable C core.
#
# This builds the dependency-free C99 core (src/meshcore_companion.c), the host
# unit test, and the Linux tty example. It deliberately does NOT build the C++
# Arduino wrapper (src/MeshCoreCompanion.{h,cpp}) -- that requires <Arduino.h>
# and is compiled by the Arduino IDE / PlatformIO instead. The Arduino manifests
# (library.properties, library.json) at the repo root are simply ignored here.
#
