# Preamble
#
cmake_minimum_required(VERSION 3.20)     # buildPresets is introduced in 3.20
project(stm32f2xx-hal)

#---
# Target exported by this project as 'stm32f2xx-hal'
#
# You must configure the HAL with some cached variables in your project:
# - STM_HAL_CONF_DIR        : [path]    directory which holds the configuration: stm32f2xx_hal_conf.h
# - STM_HAL_DEVICE          : [string]  select a supported compiler definition (e.g. 'STM32F217xx')
# - STM_USE_HAL_DRIVER      : [boolean] true = set compiler definition 'USE_HAL_DRIVER'
# - STM_USE_FULL_LL_DRIVER  : [boolean] true = set compiler definition 'USE_FULL_LL_DRIVER'
# - STM_USE_FULL_ASSERT     : [bbolean] true = set compiler definition 'USE_FULL_ASSERT'
add_subdirectory(Drivers)

# This is needed only if we are the top level project

if(CMAKE_SOURCE_DIR STREQUAL CMAKE_CURRENT_SOURCE_DIR)
  
  # Setup target which creates a source package for efficient usage with Cmake CPM/FetchContent
