/usr/local/lib64/libkinetic_client.so: undefined reference to `google::FlagRegisterer::FlagRegisterer(char const*, char const*, char const*, char const*, void*, void*)'

I use latest version of gflags, glog, kinetic-cpp-client and h-flat. When I compile h-flat, I get a failure message:
[ 24%] Linking CXX executable hflat
/usr/local/lib64/libkinetic_client.so: undefined reference to `google::FlagRegisterer::FlagRegisterer(char const*, char const*, char const*, char const*, void*, void*)'
collect2: error: ld returned 1 exit status
CMakeFiles/hflat.dir/build.make:665: recipe for target 'hflat' failed

make[1]: *** [CMakeFiles/hflat.dir/all] Error 2
Makefile:83: recipe for target 'all' failed

It seems from libkinetic_client.so, there is an unreferenced symbol. Can anybody give me some hints to pass compiling ? Thanks in advance.
