Try to execute: No graphical output
and then try to build your ROOT from scratch (i.e. first delete everything) again.
BTW. Note that with the “root-master”, you should not need to use -DCMAKE_CXX_FLAGS="-D_GLIBCXX_USE_CXX11_ABI=0" any more (which is needed with ROOT 6.06), so try: cmake -DCMAKE_INSTALL_PREFIX="${ROOT_INSTALL_DIR}" -Dcxx14="ON" -Dall="ON" -Dgeocad="ON" -Dbuiltin_ftgl="OFF" -Dbuiltin_glew="OFF" -Dsoversion="ON" ../root-master
