The option -Wl,--as-needed needs to be disabled in some way, if it's
applied globally it's certainly not compatible with libraries that
depend on other libraries (surely a fairly common occurrence?). The
link order is not a factor.
Maybe there is some official way to turn off that feature in qmake, or
to make it behave more intelligently with regard to external libraries
vs Qt libraries. Otherwise one could put the gsl library at the end
of the libraries list with -Wl,--no-as-needed:
.... -Wl,--no-as-needed -lgsl -lgslcblas -lm
