+Subject: [PATCH] configure.cmake: fix valgrind
+
+Check valgrind headers only if WITH_VALGRIND is set.
+
+mariadb uses two macros for valgrind compilations:
+HAVE_valgrind - valgrind is installed and can be set by configure option -DWITH_VALGRIND
+HAVE_VALGRIND - valgrind debug libraries is installed, set by auto check
+
+We would like to set them both by the configure option so that we can use
+PACKAGECONFIG to decide if valgrind is needed or not.
+
+Upstream-Status: Inappropriate [oe specific]
