+# wolfSSL Espressif CMake Library
+
+This directory contains common functions used in various examples and components.
+
+Instead of duplicating functions in various locations, this common library can be used.
+
+Although it can be used as-is, the intent is to include it in the published wolfSSL Managed Component and include it from there when possible.
+
+## CHECK_DUPLICATE_LIBRARIES
+
+Searches for duplicate directories containing duplicate component libraries.
+
+Parameters:
+
+- RESULT_VAR (output variable)
+- KEYWORD (e.g. "wolfssl", "wolfmqtt", etc)
