perf-persistentMap (Lunchbox) does not link; missing leveldb library in linker

[RubenGarcia]

Ubuntu 14.04.3.
Current Equalizer from today.
Running
cmake ..
make

Linking CXX executable perf-persistentMap
/usr/bin/ld: CMakeFiles/perf-persistentMap.dir/persistentMap.cpp.o: undefined reference to symbol '_ZNK7leveldb6Status8ToStringEv'
//usr/lib/x86_64-linux-gnu/libleveldb.so.1: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make[2]: *** [Lunchbox/tests/perf-persistentMap] Error 1
make[1]: *** [Lunchbox/tests/CMakeFiles/perf-persistentMap.dir/all] Error 2
make: *** [all] Error 2

Possibly due to a wrong order of the linked libraries, or a missing library, according to

adding the following option (link against libleveldb.so) works. Please fix the CMakeLists.txt. Thanks!
-lleveldb
to the offending line, so that it ends as

Once that is fixed, the rest of the build works perfectly.

Current git (Fri Nov 13 12:51:49 CET 2015) is still affected.

Closing for now, as I cannot reproduce it after recloning. However, it may be hidden by bug
#514
and it may reappear once that is fixed.

Definitely closed, I compiled Equalizer successfully.
