because of missing -fPIC opion
Description:
I need to used the object libraries for building libs out of serveral convenient
libraries.

compilation with gcc fails with
"[100%] Building CXX object CMakeFiles/a.dir/dummy.cc.o
[100%] Built target a
Linking CXX shared library libb.so
/usr/bin/ld: CMakeFiles/a.dir/dummy.cc.o: relocation R_X86_64_32 against
`_ZSt4cout' can not be used when making a shared object; recompile with -fPIC
CMakeFiles/a.dir/dummy.cc.o: could not read symbols: Bad value
collect2: error: ld returned 1 exit status
make[2]: *** [libb.so] Error 1
make[1]: *** [CMakeFiles/b.dir/all] Error 2
