# CMake build system design considerations:
|
|
#
|
|
# - Include directories:
|
|
# + Do not define include directories globally using the include_directories
|
|
# command but rather at the target level using the
|
|
# target_include_directories command. That way, it is easier to guarantee
|
|
# that targets are built using the proper list of include directories.
|
|
# + Use the PUBLIC and PRIVATE keywords to specify the scope of include
|
|
# directories. That way, a target linking to a library (using the
|
|
# target_link_libraries command) inherits from the library PUBLIC include
|
|
# directories and not from the PRIVATE ones.
|
|
# - TF_PSA_CRYPTO_TARGET_PREFIX: CMake targets are designed to be alterable by
|
|
# calling CMake in order to avoid target name clashes, via the use of
|
|
# TF_PSA_CRYPTO_TARGET_PREFIX. The value of this variable is prefixed to the
|
|
# tfpsacrypto and apidoc targets.
|
|
#
|
|
|
|
# We specify a minimum requirement of 3.10.2, but for now use 3.5.1 here
|
|
# until our infrastructure catches up.
