@@ -0,0 +1,27 @@
+The galera package itself does not need "openssl/engine.h" to compile.
+
+There are only two instanced of that include:
+
+1) File: "asio/asio/ssl/detail/openssl_types.hpp", necessary for galera itself to build
+Which contains coorectly conditioned:
+|  #if !defined(OPENSSL_NO_ENGINE)
+|  # include <openssl/engine.h>
+|  #endif // !defined(OPENSSL_NO_ENGINE)
+
+2) File: "galera-26.4.19/galerautils/tests/gu_asio_test.cpp", necessary for galera 'galerautils' tests to build
+
+which does not have the include inside a condition, as the code requires it in any case.
+
+==
+
+As a workaround, disable build of the 'galerautils' tests, until
+the openssl engine functionality is correctly removed from it.
