+Subject: [PATCH] cmake: support new libedit interface
+
+libedit changed it's interface a while ago. MariaDB's cmake file doesn't
+recognize the new interface, the compile test fails:
+
+/mariadb-10.2.19/CMakeFiles/CMakeTmp/src.cxx: In function 'int main(int, char**)':
+/mariadb-10.2.19/CMakeFiles/CMakeTmp/src.cxx:6:47: error: invalid conversion from 'char*' to 'int' [-fpermissive]
+  int res= (*rl_completion_entry_function)(0,0);
+           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~
+
+Fix this by adding a detection for the new interface as well.
+
+Run-tested on a MIPS machine.
