+   * Add MBEDTLS_TARGET_PREFIX CMake variable, which is prefixed to the mbedtls,
+     mbedcrypto, mbedx509 and apidoc CMake target names. This can be used by
+     external CMake projects that include this one to avoid CMake target name
+     clashes.  The default value of this variable is "", so default target names
+     are unchanged.
