Description:
Building Cluster 7.3.0 against a default install of memcached 1.6beta1 instead of the bundled source fails with:

 [ 80%] Built target ndbmemcache
 Linking CXX shared module ndb_engine.so
 /usr/bin/ld.gold.real: error: cannot find -lmemcached_utilities
 collect2: error: ld returned 1 exit status
 make[2]: *** [storage/ndb/memcache/ndb_engine.so] Error 1
 make[1]: *** [storage/ndb/memcache/CMakeFiles/ndb_engine.dir/all] Error 2
 make: *** [all] Error 2
 
CMake checks find the memcached_utilities library in the correct directory /usr/local/lib/memcached but this library path is not passed to the linker call for ndb_engine.so

How to repeat:
First build memcached 1.6beta1 using default configure settings (prefix=/usr/local, libraries go to /usr/local/lib/memcached)

Then build mysql cluster with "cmake -DWITH_BUNDLED_MEMCACHED=0"

Also reproducible with 7.3.2

// Install memcached
cd /tmp/

Apparently still unfixed in 7.4.1
