CMakeLists.txt (22343B)
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. 21 cmake_minimum_required(VERSION 3.5.1) 22 23 include(CMakePackageConfigHelpers) 24 25 # Include convenience functions for printing properties and variables, like 26 # cmake_print_properties(), cmake_print_variables(). 27 include(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.
