Right, in particular it means that cmake-gui uses that symbol but none
of the libraries loaded into the executable have it. I'd start with
checking what ldd says is being loaded for your cmake-gui executable.
Maybe there's another Qt installation in LD_LIBRARY_PATH that is being
used for running cmake-gui even though its been built against the Qt
in /usr/. The other common cause could be the inverse of that, its
trying to run against your system Qt but the build process has picked
up a Qt from elsewhere compiled with different flags that change the
symbols name.
