-# 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 tfpsacrypto-apidoc targets.
