How does one turn the GDML feature ON during ROOT installation?

With the precompiled bianries, I am facing now this kind of problem. In my case the error is:

/from/somewhere/$ g++ -std=c++11  mycode.cpp `root-config --glibs --cflags` -o mycode
/../Software/acad/root/lib/libImt.so: undefined reference to `tbb::interface7::internal::isolate_within_arena(tbb::interface7::internal::delegate_base&, long)'
collect2: error: ld returned 1 exit status

Following this thread I changed LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTSYS/lib to LD_LIBRARY_PATH=$ROOTSYS/lib:$LD_LIBRARY_PATHand exported… but the error remains.
