+# CMake build system design considerations:

+#     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
