# MicroPython CMake glue for pygraphics (ESP32, RP2, …).
#
# Make-based ports use micropython.mk in this directory. CMake-based ports
# (esp32, rp2, …) discover this file via USER_C_MODULES / an aggregator
# micropython.cmake that includes sibling modules.
#
# Point USER_C_MODULES at this repo (or this file) directly, e.g.:
#   idf.py build -DUSER_C_MODULES=<path to pygraphics>
# Or a semicolon-separated list with other modules (no aggregator required):
#   -DUSER_C_MODULES="<path to pygraphics>;<path to displayif>"
