1# 2# CMake build system design considerations: 3# 4# - Include directories: 5# + Do not define include directories globally using the include_directories 6# command but rather at the target level using the 7# target_include_directories command. That way, it is easier to guarantee 8# that targets are built using the proper list of include directories. 9# + Use the PUBLIC and PRIVATE keywords to specify the scope of include 10# directories. That way, a target linking to a library (using the 11# target_link_libraries command) inherits from the library PUBLIC include 12# directories and not from the PRIVATE ones. 13# - MBEDTLS_TARGET_PREFIX: CMake targets are designed to be alterable by calling 14# CMake in order to avoid target name clashes, via the use of 15# MBEDTLS_TARGET_PREFIX. The value of this variable is prefixed to the 16# mbedtls, mbedx509, mbedcrypto and apidoc targets. 17# 18 19# We specify a minimum requirement of 3.10.2, but for now use 3.5.1 here 20# until our infrastructure catches up. 21cmake_minimum_required(VERSION 3.5.1) 22 23include(CMakePackageConfigHelpers) 24 25# Include convenience functions for printing properties and variables, like 26# cmake_print_properties(), cmake_print_variables(). 27include(CMakePrintHelpers) 28 29# https://cmake.org/cmake/help/latest/policy/CMP0011.html 30# Setting this policy is required in CMake >= 3.18.0, otherwise a warning is generated.
