Jim Mussared 742037ec38 esp32/Makefile: Allow specifying BOARD_DIR on make command line.
This matches the behavior of the makefile ports but implemented for CMake,
making it easy to specify custom board definitions.

This work was funded through GitHub Sponsors.

# Makefile for MicroPython on ESP32.
#
# This is a simple, convenience wrapper around idf.py (which uses cmake).
# Select the board to build for:
ifdef BOARD_DIR
# Custom board path - remove trailing slash and get the final component of
# the path as the board name.
BOARD ?= $(notdir $(BOARD_DIR:/=))
else
# If not given on the command line, then default to GENERIC.
BOARD ?= GENERIC
BOARD_DIR ?= boards/$(BOARD)
endif
ifeq ($(wildcard $(BOARD_DIR)/.),)
$(error Invalid BOARD specified: $(BOARD_DIR))
endif
# If the build directory is not given, make it reflect the board name.
BUILD ?= build-$(BOARD)
# Device serial settings.
PORT ?= /dev/ttyUSB0
BAUD ?= 460800
PYTHON ?= python3
# Would be good to use cmake to discover submodules (see how rp2/Makefile does
# it), but on ESP32 the same trick doesn't work because "idf.py build" fails
# on berkeley-db dependency before printing out the submodule list.
# For now just force the submodule dependencies here.
